**Modules Preconditions:**

&gt;The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (`precondition=&quot;managedHandler&quot;`) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:
&gt;
&gt;     &lt;add name=&quot;FormsAuthentication&quot; type=&quot;System.Web.Security.FormsAuthenticationModule&quot; preCondition=&quot;managedHandler&quot; /&gt;
&gt;
&gt;If you remove the attribute `precondition=&quot;managedHandler&quot;`, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See &quot;[How to Take Advantage of IIS Integrated Pipeline][1]&quot; for an example of enabling ASP.NET modules to run for all content.
&gt;
&gt;You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the &quot;`managedHandler`&quot; precondition. 
&gt;
&gt;**To enable all managed modules to run for all requests without configuring each module entry to remove the &quot;`managedHandler`&quot; precondition, use the `runAllManagedModulesForAllRequests` property in the `&lt;modules&gt;` section:**
&gt;
&gt;     &lt;modules runAllManagedModulesForAllRequests=&quot;true&quot; /&gt;    
&gt;
&gt;When you use this property, the &quot;`managedHandler`&quot; precondition has no effect and all managed modules run for all requests.

I was surprised to find that Go has a [&#39;goto&#39;][1] statement. I&#39;ve always been taught that &#39;goto&#39; statements are a thing of the past and evil for it occludes the actual flow of a program, and that functions or methods are always a better way of controlling flow.

I must be missing something. Why did Google include it?

Is there any way to do the opposite of `:hover` **using only** CSS? As in: if `:hover` is `on Mouse Enter`, is there a CSS equivalent to `on Mouse Leave`?

Example:

I have a HTML menu using list items. When I hover one of the items, there is a CSS color animation from `#999` to `black`. How can I create the opposite effect when the mouse leaves the item area, with an animation from `black` to `#999`?

I am using IIS 7.5 and I have a simple web application. Do I need to write this in my web.config file.
I have also written few http handler for jquery ajax call.

Why does this simple web service refuse to return JSON to the client?

Here is my client code:

&lt;!-- language: lang-js --&gt;

            var params = { };
            $.ajax({
                url: &quot;/Services/SessionServices.asmx/HelloWorld&quot;,
                type: &quot;POST&quot;,
                contentType: &quot;application/json; charset=utf-8&quot;,
                dataType: &quot;json&quot;,
                timeout: 10000,
                data: JSON.stringify(params),
                success: function (response) {
                    console.log(response);
                }
            });

And the service:

&lt;!-- language: lang-c --&gt;

    namespace myproject.frontend.Services
    {
        [WebService(Namespace = &quot;http://tempuri.org/&quot;)]
        [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
        [System.ComponentModel.ToolboxItem(false)]
        [ScriptService]
        public class SessionServices : System.Web.Services.WebService
        {
            [WebMethod]
            [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
            public string HelloWorld()
            {
                return &quot;Hello World&quot;;
            }
        }
    }

web.config:

&lt;!-- language: lang-xml --&gt;

    &lt;configuration&gt;
        &lt;system.web&gt;
            &lt;compilation debug=&quot;true&quot; targetFramework=&quot;4.0&quot; /&gt;
        &lt;/system.web&gt;
    &lt;/configuration&gt;

And the response:

&lt;!-- language: lang-xml --&gt;

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;string xmlns=&quot;http://tempuri.org/&quot;&gt;Hello World&lt;/string&gt;

No matter what I do, the response always comes back as XML. How do I get the web service to return Json?

Here is the Fiddler HTTP trace:

I have found plenty of information out there about this error: &#39;ERROR: Could not load file or assembly &#39;*.dll&#39; or one of its dependencies. Access is denied.’ 
But i haven&#39;t found answer specific to my scenario. 
My site is deploy on 6 different production servers, only on one server i am facing this issue. The issue is random, but after it happens once, it continues until the site is recompile by done a small modification in web.config file(i know trick, after modification in web.config recompile the web application) and site on that server start working.
Yesterday, issue was reproducing after one month period of working.
We can&#39;t afford this issue on production.

I&#39;m trying to get a WCF service running in IIS8 on Windows Server 2012 build 8400.

When installing the web role the WCF stuff (under 3.51) wasn&#39;t to be found like in Windows Server 2008.

When installed the svc handler mapping was missing, so i did a:

    %windir%\Microsoft.NET\Framework\v3.0\WindowsCommunication Foundation\ServiceModelReg.exe –i

Now the handler mapping is there, but I still get:

    The resource you are looking for does not have a handler associated with it.

(I removed the static file handler.)

The site is using the classic pipeline in order to use impersonation.

I am trying to use `HttpContent`:

    HttpContent myContent = HttpContent.Create(SOME_JSON);

...but I am not having any luck finding the DLL where it is defined.

First, I tried adding references to `Microsoft.Http` as well as `System.Net`, but neither is in the list. I also tried adding a reference to `System.Net.Http` but the `HttpContent` class is not available.

So, can anyone tell me where I can find the `HttpContent` class?

I have Googled a lot and found a lot of solutions, but none of them give me the correct week number for the 2012-12-31. Even the example on MSDN ([link][1]) fails.

2012-12-31 is Monday, therefore it should be Week 1, but every method I tried gives me 53. Here are some of the methods, that I have tried:

From the MDSN Library:

    DateTimeFormatInfo dfi = DateTimeFormatInfo.CurrentInfo;
    Calendar cal = dfi.Calendar;

    return cal.GetWeekOfYear(date, dfi.CalendarWeekRule, dfi.FirstDayOfWeek);

Solution 2:

    return new GregorianCalendar(GregorianCalendarTypes.Localized).GetWeekOfYear(date, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);

Solution 3:

    CultureInfo ciCurr = CultureInfo.CurrentCulture;
    int weekNum = ciCurr.Calendar.GetWeekOfYear(dtPassed, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
    return weekNum;


  [1]: http://msdn.microsoft.com/en-us/library/system.globalization.calendar.getweekofyear.aspx



**Update**

The following method actually returns 1 when date is 2012-12-31. In other words, my problem was that my methods were not following the ISO-8601 standard.

    // This presumes that weeks start with Monday.
    // Week 1 is the 1st week of the year with a Thursday in it.
    public static int GetIso8601WeekOfYear(DateTime time)
    {
        // Seriously cheat.  If its Monday, Tuesday or Wednesday, then it&#39;ll 
        // be the same week# as whatever Thursday, Friday or Saturday are,
        // and we always get those right
        DayOfWeek day = CultureInfo.InvariantCulture.Calendar.GetDayOfWeek(time);
        if (day &gt;= DayOfWeek.Monday &amp;&amp; day &lt;= DayOfWeek.Wednesday)
        {
            time = time.AddDays(3);
        }

        // Return the week of our adjusted day
        return CultureInfo.InvariantCulture.Calendar.GetWeekOfYear(time, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
    }

Get the correct week number of a given date

I am building a site in which i would like to create a file client side from the value of a textarea element.

I have the code in place to do this, but i am getting this error

&gt; HTTP Error 404.15 - Not Found The request filtering module is
&gt; configured to deny a request where the query string is too long.

Is there a way to override this so that I am able to process requests of any size?

If not, is there a way to generate files client side without using the filesystem/active x object?

thanks

How to configure the web.config to allow requests of any length

I deployed my MVC-3 application on windows Azure. But now when I am requesting it through `staging url` it shows me **(Sorry, an error occurred while processing your request.)**. Now I want to see the full error message, by default it is hiding that because of some security reasons. I know that we can do this through web.config file. But how?

How to set web.config file to show full error message

I have some IIS rewrite rules that I want to vary by environment. The development rewrite rules are in the web.config file, then at the end of the web.test.config file I have:

    

        &lt;appSettings&gt;
             ...Some app settings tranforms here
        &lt;/appSettings&gt;
        &lt;system.webserver&gt;
                &lt;rewrite xdt:Transform=&quot;Replace&quot;&gt;
                  &lt;rules&gt;
                    ... rules here
                  &lt;/rules&gt;
                &lt;/rewrite&gt;
              &lt;/system.webserver&gt;
            &lt;/configuration&gt;

My app settings are getting transformed when I deploy to test, but by IIS rewrite rules are not. I was hoping the entire `&lt;rewrite&gt;` section would simply be replaced with the one in the transform file (as per http://msdn.microsoft.com/en-us/library/dd465326.aspx), but nothing is changing.

I have tried putting `xdt:Transform=&quot;Replace&quot; xdt:Locator=&quot;Match(name)&quot;&gt;` on the individual rules too:

    &lt;rule name=&quot;Test rule&quot; stopProcessing=&quot;true&quot; xdt:Transform=&quot;Replace&quot; xdt:Locator=&quot;Match(name)&quot;&gt;

But again this makes no difference.

Is it even possible to replace rewrite rules in the web.config and if so, what am I missing?


Replacing IIS rewrite rules in web.config transform

I&#39;m wondering how the `ConfigurationManager.AppSettings[Key]` works.

Does it read from the physical file each time I need a key? If so, should I be reading all the app settings of my web.config in a cache and then read from it?  

Or does ASP.NET or IIS load the web.config file only once at application startup?

How do I verify whether the physical file is accessed by each read? If I change the web.config, IIS restarts my application, so I can&#39;t verify it that way.


Does ConfigurationManager.AppSettings[Key] read from the web.config file each time?

This is my `web.config` mail settings:

    &lt;system.net&gt;

          &lt;/smtp&gt;
        &lt;/mailSettings&gt;
      &lt;/system.net&gt;

and here&#39;s how I try to read the values from `web.config`

     var smtp = new System.Net.Mail.SmtpClient();
     var credential = new System.Net.Configuration.SmtpSection().Network;
                    
     string strHost = smtp.Host;
     int port = smtp.Port;
     string strUserName = credential.UserName;
     string strFromPass = credential.Password;

But credentials are always null. How can i access these values?
