OnClick Run SQL Code Output To Specific DIV

Mar 9, 2011

Basically when a user clicks a button I have a javascript code that runs that displays the hidden DIV, my question is how do I make it so when the users click it executes the SQL code (which is already written to select the data) and then it displays it in the DIV that I want. Would the only way to do this be add a label to the DIV and then use LabelName.Text to populate it or can this be accomplished some other way? I am using Visual Studio 2008 and coding in c#.

C# - How To Simulate Http Request Using WatiN With Specific HTTP Referrer And Query String

Dec 6, 2010

When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.

Output Caching In HTTP Handler And SetValidUntilExpires?

Jun 8, 2010

I'm using output caching in my custom HTTP handler in the following way:

public void ProcessRequest(HttpContext context)
{
TimeSpan freshness = new TimeSpan(0, 0, 0, 60);
context.Response.Cache.SetExpires(DateTime.Now.Add(freshness));
context.Response.Cache.SetMaxAge(freshness);
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.Cache.SetValidUntilExpires(true);
...
}

It works, but the problem is that refreshing the page with F5 leads to page regeneration (instead of cache usage) despite of the last codeline:

context.Response.Cache.SetValidUntilExpires(true);

UPD: Seems like the cause of problem is that HTTP handler response isn't caching on server. The following code works well for web-form, but not for handler:

Response.Cache.SetCacheability(HttpCacheability.Server);

Are there some specifics of the caching the http handler response on server?

Outputstream - Can Get Read Access To The HTTP Output Stream In Web Application

Feb 22, 2010

I would like to read all content that's been written to the output stream. I'm attempting to do this using an HTTP module, and it seems like the obvious timing would be when handling the PreSendRequestContent event.

However, if the output stream seems to be set to write-only, as I can't read using a StreamReader. Is there a way I read and re-write the content without writing my own IIS module?

Pass Value From One App To Another Via HTTP Header?

Jun 15, 2010

We are implementing a single sign on mechanism in an enterprise environment, where the token is shared between applications using HTTP header. Now, in order to do the integration test, I need to write an application to simulate this. Is there any way in ASP.NET where I can redirect to another web-page and pass a custom HTTP header in the process?

HTTP Response Differences Between Browser's View Source And Netcat's Output?

Jun 10, 2010

I'm looking at a website using Internet Explorer and Firefox. In each browser I select view source and see the website's URL in the links. These links were concatenated together using HttpContext.Current.Request.Url.Host in the code behind. However, when I use netcat or Burp Suite v1.3.03, looking at the same links I see the servername instead of the website's URL.

My question is - Why does view source in the browser display different links in the page source than what netcat or Burp Suite outputs? Is the browser rewriting stuff?

My thought to correct is to have a web.config setting which is used to create the links.

Next question - Does anyone know of a configuration change to make to IIS to return the URL instead of the server name or a .NET function that I should be calling instead to get the URL that the website is running as.

Response - Get Custom Http Header?

May 14, 2010

I have an asp.net appliction on the one server. There I've added code on server-side in Page_Load:

Response.AddHeader("key", "password-key-from-hotel");

On the client side I have a form:
<form ... action="www.link-to-another-domaint" >
<input type="hidden" id="asd" value="fgh" >
....
</form>
<script type="text/javascript">
document.forms[0].submit();
</script>

Then on the other domain - there is also my other application - I'm trying to get the hedaer "key" by this code:

Request.Headers["key"].ToString();

But there is no such header. Is there is a desicion? Where is my mistake?

Emulate Specific HTTP Headers?

Oct 5, 2010

I Have a specific set of HTTP response headers I'm trying to recreate in ASP.NET.
Here is how it looks in Fiddler (Raw):

HTTP/1.1 200 OK
Content-Length: 570746
Content-Type: audio/wav
Last-Modified: Wed, 19 May 2010 00:44:38 GMT
Accept-Ranges: bytes
ETag: "379d676ecf6ca1:3178"
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
Date: Tue, 05 Oct 2010 18:35:18 GMT

Here is how it looks on the Headers tab (same data. Different view)

I am trying to recreate the same set of headers (different values of course) with code, on an ASP.NET page. The biggest problem is with the cache settings and the ETag. It usually shows some "private" or similar cache setting and no ETag value, even though I'm trying to set it explicitly with

Response.Cache.SetETag

IIS7 Rewrite - Strip HTTP Header?

Apr 1, 2010

Is it at all possible to use IIS7's rewrite capability in web.config to strip a particular HTTP header from a client request?We have an application that makes an HTTP POST to our website, and apparently the request contains the HTTP Expect header. Previously this was not a problem, but we've switched hosts and now the site is returning HTTP error 417 Expectation failed. So the real solution is to fix the software so it doesn't send the Expect header, but that can't happen soon enough for the folks in charge, who'd like to come up with an immediate web-based fix.I've used ISAPI_Rewrite before and I've read that it can strip a header, and the new host claimed they had ISAPI installed... but that seems to have been a lie, as I cannot get it to work, and support's only response on the subject is "use IIS7 Rewrite instead."

Can't Set HTTP Vary Header In IIS7 Classic Mode

Jan 16, 2010

First, a little background. I have written a custom HTTP compression module for ASP.NET. My development machine has Windows 7 Ultimate, which comes with IIS7. My production environment uses IIS6.

The problem I'm having is, Resource Expert Droid (redbot.org) tells me that I need to add a header to my response to properly support compression: "Vary: Accept-Encoding"

On IIS7 in integrated mode, it works properly. However, in classic mode, which is how my application ultimately runs, I cannot get my code to output this header using any of Response.AppendHeader(), Response.Cache.SetVaryByCustom(), or Response.Cache.VaryByHeaders.

IIS7 Overwriting Defined HTTP Header Values?

Oct 21, 2010

I am attempting to set the content-type of an asp.net .ashx file to text/plain.

When I run this through the ASP.NET Development Server, the content-type is properly set. When I serve it through IIS7, however, the content-type (and any other header values I set) don't come through (it came through as text/html).

The only value set in the HTTP Response Headers section of IIS Manager is the X-Powered-By attribute. I tried setting the content-type here, but that didn't work. But if I removed the X-Powered-By attribute, it was removed from the header.

AJAX :: Server Did Not Recognize The Value Of HTTP Header SOAPAction?

Mar 3, 2010

I got the error when I called a webservice

---- Server did not recognize the value of HTTP Header SOAPAction: http://tempuri.org/GetBestBidOfferData.

The odd thing is that I have several methods in this webservice, and only two of them got me the error message. It used to work, but then gave me the error message after i added some other methods to the asmx file.

The namespace should be the same for all the methods. One more thing to note is: these two methods had return data type DataTable before, and I changed it to DataSet. It should not affect anything, I assume.

C# - Cache-Control HTTP Header Does Work Properly?

Mar 22, 2011

I am having issue with cache-control. I have one IIS website with multiple host headers. When you browse site number 1 then cache will be set for this site, when you open browser again and go to 2nd site you will see content from first site. How can I determine cache content based on the site user visits? Everything working fine when you have 1 site and host header related to SAME site.

//Set Cacheability
if (!Context.User.Identity.IsAuthenticated && _activeNode.CacheDuration > 0)
{
var eTag = GetETag(_activeNode);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);

Bypass The X-Frame-Options: SAMEORIGIN HTTP Header?

May 6, 2010

I am developing a web page that needs to display, in an iframe, a report served by another company's SharePoint server. They are fine with this. The page we're trying to render in the iframe is giving us X-Frame-Options: SAMEORIGIN which causes the browser (at least IE8) to refuse to render the content in a frame. First, is this something they can control or is it something SharePoint just does by default? If I ask them to turn this off, could they even do it? Second, can I do something to tell the browser to ignore this http header and just render the frame?
