So the iFrame isn&#39;t actually setting the `u` cookie for the runwithfriends.appspot.com domain. What Facebook does is it creates a form, `&lt;form action=&quot;runwithfriends.appspot.com/...&quot; target=&quot;name_of_iframe&quot; method=&quot;POST&quot;&gt;` and uses javascript to submit the form on page load. Since the form&#39;s target is the iframe, it doesn&#39;t reload the page... it just loads the iframe with the POST&#39;s response. Apparently even Chrome and other browsers with strict cookie policies set cookies for cross domain requests if they are POST requests...

This is confusing me:

As far as I have read, a view with setVisibility(View.GONE); should not receive any more touch- or click events.
My layout has two parts, which will be visible or gone so that only one of them is visible and usable at a time but View.GONE doesn&#39;t do the trick.
I can&#39;t see the GONE view, as expected, but it still reacts to onClick (and consumes the event the other view should get).

Can you help me?

_Maybe of interest:
When I start my project one view is GONE, the other visible. This time it will work as expected (the GONE view is basically ignored), but after setting View.GONE through the code it&#39;ll stop working._

android View with View.GONE still receives onTouch and onClick

I have a thread downloading data and I want to wait until the download is finished before I load the data.  Is there a standard way of doing this?

More Info:

I have a Download class that gets data from a URL (Serialized POJOs).  Download is Runnable and Observable.  It keeps track of the bytes downloaded and download size.  I have a progress bar that displays the progress to the User.   The GUI observes Download to update the progress bar.

When the POJO is downloaded I want to get it and move to the next step.  Each step has to wait for the previous to finish.  The problem is I cant think of a way to pause my application to wait for the download thread.  Once the download is finished I want to call `download.getObject()` which will return the data as an object.  I can then cast it and get on with the next download.

I have a helper class that manages the URLs for download and makes all of the calls to Download.  This call will call getObject and do the casting.  The Gui calls `helper.getUser()`. helper starts the thread running and I want it to &#39;know&#39; when it is finished so it can return the casted object. 

Any suggestions/examples? I am in the beginning stages of this design so I am willing to change it.

**Update:**

I followed [http://download.oracle.com/javase/6/docs/api/javax/swing/SwingWorker.html#get][1] and used modal to block until the thread finished.  The code was very messy and I don&#39;t like this approach.  I will keep trying to find a &#39;clean&#39; way to handle the workflow of the download processes.

I was browsing Facebook&#39;s documentation reading about canvas applications and I came across an example application: http://developers.facebook.com/docs/samples/canvas. As I read through their example, however, I got very confused about their use of cookies in the iframe application.

A little backstory...

I had already played around with using iframes for embeddable widgets (unrelated to Facebook) and I found out a few browsers (Chrome, Safari, etc.) have strict cookie policies and don&#39;t allow cross-domain cookies set in iframes (Firefox, on the other hand, allows iframes to set cross-domain cookies in iframes). For example, if foo.com has an iframe with `src=&quot;http://bar.com/widget&quot;` the iframe widget will not be able to set any cookies for bar.com and therefore will have trouble persisting state within the iframe: bar.com will interpret every request (including ajax requests) from the widget as a fresh request without an established session. I struggled, and found a way around this by using JSONP and javascript to set cookies for foo.com instead...

... and so?

Well, I was looking at the example canvas iframe Facebook application and I noticed that their application (hosted on runwithfriends.appspot.com) is able to set a cookie, `u`, with the current user&#39;s id along with a few other parameters for the runwithfriends.appspot.com domain. It sends this cookie with every request... and it works in both Chrome and Firefox! WTF? How does Facebook get around the cross-domain cookie restrictions on Chrome?

(I already know the answer now, but I thought this might be helpful for anyone struggling to figure out the same thing -- I&#39;ll post the answer below.)

How can I create and read a value from a cookie in JavaScript?

How do I create and read a value from cookie?

I&#39;m a bit confused as to how cookies work with Scrapy, and how you manage those cookies.

This is basically a simplified version of what I&#39;m trying to do:
![enter image description here][1]


----------


The way the website works:
--------------------------

When you visit the website you get a session cookie.

When you make a search, the website remembers what you searched for, so when you do something like going to the next page of results, it knows the search it is dealing with.


----------


My script:
----------

My spider has a start url of searchpage_url

The searchpage is requested by `parse()` and the search form response gets passed to `search_generator()`

`search_generator()` then `yield`s lots of search requests using `FormRequest` and the search form response.

Each of those FormRequests, and subsequent child requests need to have it&#39;s own session, so needs to have it&#39;s own individual cookiejar and it&#39;s own session cookie.


----------


I&#39;ve seen the section of the docs that talks about a meta option that stops cookies from being merged. What does that actually mean? Does it mean the spider that makes the request will have its own cookiejar for the rest of its life?

If the cookies are then on a per Spider level, then how does it work when multiple spiders are spawned? Is it possible to make only the first request generator spawn new spiders and make sure that from then on only that spider deals with future requests?

I assume I have to disable multiple concurrent requests.. otherwise one spider would be making multiple searches under the same session cookie, and future requests will only relate to the most recent search made?

I&#39;m confused, any clarification would be greatly received!


----------


EDIT:
-----

Another options I&#39;ve just thought of is managing the session cookie completely manually, and passing it from one request to the other.

I suppose that would mean disabling cookies.. and then grabbing the session cookie from the search response, and passing it along to each subsequent request.

Is this what you should do in this situation?

Scrapy - how to manage cookies/sessions

Ok, so I really think I am doing this right, but the cookies aren&#39;t being cleared.

     Session.Clear();
     HttpCookie c = Request.Cookies[&quot;MyCookie&quot;];
     if (c != null)
     {
         c = new HttpCookie(&quot;MyCookie&quot;);
         c[&quot;AT&quot;] = null;
         c.Expires = DateTime.Now.AddDays(-1);
         Request.Cookies.Add(c);
     }

     return RedirectToAction(&quot;Index&quot;, &quot;Home&quot;);

When the redirect happens, it finds the cookie again and moves on as though I never logged out. Any thoughts?



How do you clear cookies using asp.net mvc 3 and c#?

I looked in many questions about cookies but I didn&#39;t find an answer on my problem. I have following scenario:

A user creates a login on *example.com* and should get a cookie but only for the subdomain *fuu.example.com*. I generate following HTTP header part:

    Set-Cookie: name=TestUser; Domain=fuu.example.com; Path=/; secure; HttpOnly 

But when I make a request to *https://fuu.example.com*, the cookie will be not added to the request. I wonder if it is possible that *example.com* sets a cookie for `fuu.example.com`. I know that it is possible that *example.com* set a cookie for `.example.com` also for all subdomains for *example.com* but that&#39;s not what I want. 

How do I set a cookie for a subdomain? I am not seeing the cookie in a request to the subdomain.

Domain set cookie for subdomain

For my authentication process I create a unique token when a user logs in and put that into a cookie which is used for authentication.

So I would send something like this from the server:

    Set-Cookie: token=$2a$12$T94df7ArHkpkX7RGYndcq.fKU.oRlkVLOkCBNrMilaSWnTcWtCfJC; path=/;

Which works on all browsers. Then to delete a cookie I send a similar cookie with the `expires` field set for January 1st 1970

    Set-Cookie: token=$2a$12$T94df7ArHkpkX7RGYndcq.fKU.oRlkVLOkCBNrMilaSWnTcWtCfJC; path=/; expires=Thu, Jan 01 1970 00:00:00 UTC; 

And that works fine on Firefox but doesn&#39;t delete the cookie on IE or Safari.

So what is the best way to delete a cookie (without JavaScript preferably)? The set-the-expires-in-the-past method seems bulky. And also why does this work in FF but not in IE or Safari?

in HTML5 the iframe has new attributes like &#39;seamless&#39; that should remove borders and scrollbars. I&#39;ve tried it but doesn&#39;t seem to work, I still can see scrollbars and borders (I&#39;m using Google Chrome as browser), Here&#39;s my code:

    &lt;iframe seamless=&quot;seamless&quot; title=&quot;google&quot; width=&quot;600&quot; height=&quot;300&quot; src=&quot;http://www.google.co.uk&quot;&gt;&lt;/iframe&gt;

Any idea why it&#39;s not working?

One more question, is it possible to target a specific section of the page inside the iframe?

I have a facebook canvas application that runs in an iframe.  I would like to debug my page in firebug but can not get the javascript to scope to the iframe that is running my app.  

the iframe:

    &lt;iframe frameborder=&quot;0&quot; src=&quot;[app_url_removed]&quot; name=&quot;iframe_canvas&quot; id=&quot;iframe_canvas&quot; class=&quot;canvas_iframe_util&quot; style=&quot;height: 905px;&quot;&gt;&lt;/iframe&gt;

i&#39;ve tried all the following and none of them work:

    cd(iframe_canvas)
    cd(window.iframe_canvas)
    cd(iframe_canvas.window)
    cd($(&#39;iframe_canvas&#39;))

I have firefox 3.6.13
and I have tried firebug 1.7a11 and firebug 1.6.2

also tried the bookmarklet and various other things from this link https://stackoverflow.com/questions/2495313/firebug-and-jquery-selectors-in-an-iframe to no avail.


firebug: how to cd to an iframe

I&#39;m trying to display an iframe in my mobile web application, but I&#39;m having trouble restricting the size of the iframe to the dimensions of the iPhone screen. The height and width attributes on the iframe element seem to have no effect, strangely. Surrounding it with a div manages to constrain it, but then I&#39;m unable to scroll within the iframe.

So I&#39;ve spent way to much time on this, and it seems to me like it should be a simple fix. I&#39;m trying to use Facebook&#39;s Authentication to register users on my site, and I&#39;m trying to do it server side. I&#39;ve gotten to the point where I get my access token, and when I go to:

https://graph.facebook.com/me?access_token=MY_ACCESS_TOKEN

I get the information I&#39;m looking for as a string that&#39;s like this:

&gt; `{&quot;id&quot;:&quot;123456789&quot;,&quot;name&quot;:&quot;John Doe&quot;,&quot;first_name&quot;:&quot;John&quot;,&quot;last_name&quot;:&quot;Doe&quot;,&quot;link&quot;:&quot;http:\/\/www.facebook.com\/jdoe&quot;,&quot;gender&quot;:&quot;male&quot;,&quot;email&quot;:&quot;jdoe\u0040gmail.com&quot;,&quot;timezone&quot;:-7,&quot;locale&quot;:&quot;en_US&quot;,&quot;verified&quot;:true,&quot;updated_time&quot;:&quot;2011-01-12T02:43:35+0000&quot;}`


It seems like I should just be able to use `dict(string)` on this but I&#39;m getting this error:

&gt; `ValueError: dictionary update sequence element #0 has length 1; 2 is required`

So I tried using Pickle, but got this error:

&gt; `KeyError: &#39;{&#39;`

I tried using `django.serializers` to de-serialize it but had similar results. Any thoughts? I feel like the answer has to be simple, and I&#39;m just being stupid. Thanks for any help!

Integrating Multiple Social networks into Android with a single common Framework or API or JAR


 **For iPhone we have ShareKit, which integrates multiple sharing options in one framework.
http://www.getsharekit.com/**

For android i have no idea if something similar exists. I am building an application which shares information to social networks, like some posts and tweets. Its a simple game, where gamers publish updates about their achievements and levels.. etc.. I used Facebook and twitter APIs but they take up lots of memory and difficult to manage. Also i cannot handle them efficiently. Any help on how to integrate them would be appreciated.

I would like to have a few suggestions on this..
