Does one of the subdomains use an underscore?
IE has problems accepting cookies from subdomains that don&#39;t follow the [URI RFC](http://www.ietf.org/rfc/rfc2396.txt).

According to [RFC1035][1] (Domain names - implementation and specification): 

&gt; [domain names] must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen.

Turns out some of the domains had an underscore ( &quot;_&quot; ) in them: `some_domain.example.com`. Although this is a violation of the RFC, all other browsers work normally.

**MSIE 7, on a domain with an underscore, silently drops all cookies for that host** and refuses to accept new ones.

The only solution is to use RFC-compliant domains (I&#39;ve replaced all the &quot;_&quot;s with &quot;-&quot;s and set up a RewriteRule so that traffic is redirected to the compliant domains).


  [1]: http://www.faqs.org/rfcs/rfc1035.html

The problem doesn&#39;t only apply for underscores in domain names, but also for domain names starting with a numeric digit. So `1aaaaaaa.tld` is actually a non-standard domain name, which will cause IE to reject the cookie.

I solved it by using only `www2.1aaaaaaa.tld`, and then adding rewrite rules for the `1aaaaaaa.tld` and `www.1aaaaaaa.tld` hosts in `.htaccess`. Don&#39;t know if that really qualifies as a standards-compliant solution.... but anyway, it seems to have solved the cookie problem.

Hope that helps someone!


Isn&#39;t there a (simple) way to tell Linq To SQL classes that a particular DateTime property should be considered as UTC (i.e. having the Kind property of the DateTime type to be Utc by default), or is there a &#39;clean&#39; workaround?

The time zone on my app-server is not the same as the SQL 2005 Server (cannot change any), and none is UTC. When I persist a property of type DateTime to the dB I use the UTC value (so the value in the db column is UTC), but when I read the values back (using Linq To SQL) I get the .Kind property of the DateTime value to be &#39;Unspecified&#39;.

The problem is that when I &#39;convert&#39; it to UTC it is 4 hours off. This also means that when it is serialized it it ends up on the client side with a 4 hour wrong offset (since it is serialized using the UTC).  

Linq to SQL DateTime values are local (Kind=Unspecified) - How do I make it UTC?

I have a one-to-one relationship but hibernatetool complains when generating the schema. Here&#39;s an example that shows the problem:

    @Entity
    public class Person {
        @Id
        public int id;
    
        @OneToOne
        public OtherInfo otherInfo;

        rest of attributes ...
    }

Person has a one-to-one relationship with OtherInfo:

    @Entity
    public class OtherInfo {
        @Id
        @OneToOne(mappedBy=&quot;otherInfo&quot;)
        public Person person;

        rest of attributes ...
    }

Person is owning side of OtherInfo. OtherInfo is the owned side so person uses `mappedBy` to specify the attribute name &quot;otherInfo&quot; in Person.

I get the following error when using hibernatetool to generate the database schema:

    org.hibernate.MappingException: Could not determine type for: Person, at table: OtherInfo, for columns: [org.hibernate.mapping.Column(person)]
            at org.hibernate.mapping.SimpleValue.getType(SimpleValue.java:292)

            at org.hibernate.tool.hbm2ddl.SchemaExport.&lt;init&gt;(SchemaExport.java:128)
            ...

Any idea why? Am I a doing something wrong or is this a Hibernate bug?



JPA Hibernate One-to-One relationship

I have a site, e.g. `example.com`, where users can set their own subdomains (one user - one subdomain) and upload their own scripts, e.g. `http://somedomain.example.com/xyzzy.php` would map to `/www/somedomain/xyzzy.php`

Now, on some of those domains, Internet Explorer 7 won&#39;t/can&#39;t accept cookies. Checked with Fiddler: the server sends Set-Cookie response correctly, yet the cookie never shows up in IE - for JS or Developer Tools. On request, IE7 doesn&#39;t send the Cookie header either.

The cookies are set for the user&#39;s domain (e.g. `somedomain.example.com`), path is `/`, tried different expiration options (past, future, current, &quot;0&quot;), are not HttpOnly, are not secure.

FF, Opera, Safari and Chrome all work without problems.

Why does IE ignore the cookies?

Everything else in my site seems to be compatible with all browsers except for my links.  They appear on the page, but they do not work.  My code for the links are as follows-

Button inside of anchor link works in Firefox but not in Internet Explorer?

I want to target IE7 and IE8 with W3C-compliant CSS. Sometimes fixing CSS for one version does not fix for the other. How can I achieve this?

How does one target IE7 and IE8 with valid CSS?

I was working on an AJAX-enabled asp.net application.
I&#39;ve just added some methods to Array.prototype like

    Array.prototype.doSomething = function(){
       ...
    }

This solution worked for me, being possible reuse code in a &#39;pretty&#39; way.

But when I&#39;ve tested it working with the entire page, I had problems..
We had some custom ajax extenders, and they started to behave as the unexpected: some controls displayed &#39;undefined&#39; around its content or value.

What could be the cause for that? Am I missing something about modifing the prototype of standart objects?

Note: I&#39;m pretty sure that the error begins when I modify the prototype for Array. It should be only compatible with IE.

adding custom functions into Array.prototype

Following is my JavaScript (mootools) code:

&lt;!-- language: lang-js --&gt;

    $(&#39;orderNowForm&#39;).addEvent(&#39;submit&#39;, function (event) {
        event.preventDefault();
        allFilled = false;
        $$(&quot;.required&quot;).each(function (inp) {
            if (inp.getValue() != &#39;&#39;) {
                allFilled = true;
            }
        });
    
        if (!allFilled) {
            $$(&quot;.errormsg&quot;).setStyle(&#39;display&#39;, &#39;&#39;);
            return;
        } else {
            $$(&#39;.defaultText&#39;).each(function (input) {
                if (input.getValue() == input.getAttribute(&#39;title&#39;)) {
                    input.setAttribute(&#39;value&#39;, &#39;&#39;);
                }
            });
        }
    
        this.send({
            onSuccess: function () {
                $(&#39;page_1_table&#39;).setStyle(&#39;display&#39;, &#39;none&#39;);
                $(&#39;page_2_table&#39;).setStyle(&#39;display&#39;, &#39;none&#39;);
                $(&#39;page_3_table&#39;).setStyle(&#39;display&#39;, &#39;&#39;);
            }
        });
    });

In all browsers except IE, this works fine. But in IE, this causes an error. I have IE8 so while using its JavaScript debugger, I found out that the `event` object does not have a `preventDefault` method which is causing the error and so the form is getting submitted. The method is supported in case of Firefox (which I found out using Firebug).

Any Help?


event.preventDefault() function not working in IE

I&#39;m having a serious issue with Internet Explorer caching results from a JQuery Ajax request.

I have header on my web page that gets updated every time a user navigates to a new page. Once the page is loaded I do this

    $.get(&quot;/game/getpuzzleinfo&quot;, null, function(data, status) {
        var content = &quot;&lt;h1&gt;Wikipedia Maze&lt;/h1&gt;&quot;;
        content += &quot;&lt;p class=&#39;endtopic&#39;&gt;Looking for &lt;span&gt;&lt;a title=&#39;Opens the topic you are looking for in a separate tab or window&#39; href=&#39;&quot; + data.EndTopicUrl + &quot;&#39; target=&#39;_blank&#39;&gt;&quot; + data.EndTopic + &quot;&lt;a/&gt;&lt;/span&gt;&lt;/p&gt;&quot;;
        content += &quot;&lt;p class=&#39;step&#39;&gt;Step &lt;span&gt;&quot; + data.StepCount + &quot;&lt;/span&gt;&lt;/p&gt;&quot;;
        content += &quot;&lt;p class=&#39;level&#39;&gt;Level &lt;span&gt;&quot; + data.PuzzleLevel.toString() + &quot;&lt;/span&gt;&lt;/p&gt;&quot;;
        content += &quot;&lt;p class=&#39;startover&#39;&gt;&lt;a href=&#39;/game/start/&quot; + data.PuzzleId.toString() + &quot;&#39;&gt;Start Over&lt;/a&gt;&lt;/p&gt;&quot;;
    
        $(&quot;#wikiheader&quot;).append(content);
    
    }, &quot;json&quot;);

It just injects header info into the page. You can check it out by going to [www.wikipediamaze.com][1] and then logging in and starting a new puzzle.

In every browser I&#39;ve tested (Google Chrome, Firefox, Safari, Internet Explorer) it works great **except** in IE. Eveything gets injected just fine in IE **the first time** but after that it never even makes the call to `/game/getpuzzleinfo`. It&#39;s like it has cached the results or something.

If I change the call to `$.post(&quot;/game/getpuzzleinfo&quot;, ...` IE picks it up just fine. But then Firefox quits working.

Can someone please shed some light on this as to why IE is caching my `$.get` ajax calls?

**UPDATE**

Per the suggestion below, I&#39;ve changed my ajax request to this, which fixed my problem:

    $.ajax({
        type: &quot;GET&quot;,
        url: &quot;/game/getpuzzleinfo&quot;,
        dataType: &quot;json&quot;,
        cache: false,
        success: function(data) { ... }
    });

How do you remove a cookie in a Java servlet?

I tried this:
http://www.jguru.com/faq/view.jsp?EID=42225

EDIT: The following now works successfully it appears to be the combination of:

    response.setContentType(&quot;text/html&quot;);
and

    cookie.setMaxAge(0);

Before I was doing:

    //remove single signon cookie if it hasn&#39;t been validated yet
    response.setContentType(&quot;text/html&quot;);
    Cookie cookie = new Cookie(SSORealm.SSO_COOKIE_NAME, &quot;&quot;);
    cookie.setDomain(SSORealm.SSO_DOMAIN);
    cookie.setMaxAge(-1);
    cookie.setPath(&quot;/&quot;);
    cookie.setComment(&quot;EXPIRING COOKIE at &quot; + System.currentTimeMillis());
    response.addCookie(cookie);

Which expires the cookie when the browser is closed as per [the documentation][1].

&gt; A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted. 


The full working snippet to expire a cookie is:

    //remove single signon cookie if it hasn&#39;t been validated yet
    response.setContentType(&quot;text/html&quot;);
    Cookie cookie = new Cookie(SSORealm.SSO_COOKIE_NAME, &quot;&quot;);
    cookie.setDomain(SSORealm.SSO_DOMAIN);
    cookie.setMaxAge(0);
    cookie.setPath(&quot;/&quot;);
    cookie.setComment(&quot;EXPIRING COOKIE at &quot; + System.currentTimeMillis());
    response.addCookie(cookie);

How do you remove a Cookie in a Java Servlet

So some guy at some other company thought it would be awesome if instead of using soap or xml-rpc or rest or any other reasonable communication protocol he just embedded all of his response as cookies in the header.

I need to pull these cookies out as hopefully an array from this curl response.  If I have to waste a bunch of my life writing a parser for this I will be very unhappy.

Does anyone know how this can simply be done, preferably without writing anything to a file?

I will be very grateful if anyone can help me out with this.

how to get the cookies from a php curl into a variable

I go to a forum which uses vBulletin 3.8. When I log in, I use firebug to see what cookies were set. I see these cookies:

&gt; __utmb, __utmc, __utma, __utmz, bbsessionhash, vbseo_loggedin, bbpassword, bbuserid, bblastactivity, bblastvisit

They all had a value set, and the domain was identical. 

But when I use JavaScript to view them, it only saw these cookies:
&gt; __utmb, __utmc, __utma, __utmz, vbseo_loggedin,  bblastactivity, bblastvisit

In firebug, I only see these three cookies: bbsessionhash, bbpasword and bbuserid, that were actually set. HTTPOnly in column HTTPOnly. What does it mean and is that the reason I can&#39;t see those cookies in JavaScript using `document.cookie`?

Why doesn&#39;t document.cookie show all the cookie for the site?

Due to weird domain/subdomain cookie issues that I&#39;m getting, I&#39;d like to know how browsers handle cookies. If they do it in different ways, it would also be nice to know the differences.

In other words - when a browser receives a cookie, that cookie MAY have a domain and a path attached to it. Or not, in which case the browser probably substitutes some defaults for them. Question 1: what are they?

Later, when the browser is about to make a request, it checks its cookies and filters out the ones it should send for that request. It does so by matching them against the requests path and domain. Question 2: what are the matching rules?
&lt;hr/&gt;
**Added:**

The reason I&#39;m asking this is because I&#39;m interested in some edge cases. Like:

 * Will a cookie for `.example.com` be available for `www.example.com`?
 * Will a cookie for `.example.com` be available for `example.com`?
 * Will a cookie for `example.com` be available for `www.example.com`?
 * Will a cookie for `example.com` be available for `anotherexample.com`?
 * Will `www.example.com` be able to set cookie for `example.com`?
 * Will `www.example.com` be able to set cookie for `www2.example.com`?
 * Will `www.example.com` be able to set cookie for `.com`?
 * Etc.

**Added 2:**

Also, could someone suggest how I should set a cookie so that:

 * It can be set by either `www.example.com` or `example.com`;
 * It is accessible by both `www.example.com` and `example.com`.

How do browser cookie domains work?

How to dynamically, via javascript, delete a session cookie, without manually restarting the browser?

I read somewhere that session cookie is retained in browser memory and will be removed when the browser is closed.

    // sessionFooCookie is session cookie
    // this code does not delete the cookie while the browser is still on
    jQuery.cookie(&#39;sessionFooCookie&#39;, null);

Thanks.

&gt; More Info: The code snippet above is a
&gt; javascript code snippet, using jQuery
&gt; and its jQuery.cookie plugin.
