C# - HTTP 502 Proxy Error - The Size Of The Response Header Is Too Large. Contact Your ISA Server Administrator. (12216)
Feb 23, 2011
Some of my users are getting the following error
HTTP 502 Proxy Error - The size of the response header is too large. Contact your ISA server administrator. (12216) Internet Security and Acceleration Server
I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.
I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.
I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
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?
I have a DTS script which transforms a Tab delimited text file to a table. I get the following error when trying to transform the data of a field that is greater than 255 chars:

I have seen this issue with importing from Excel with the jet 4.0 engine, however I am importing a text file.
When the user selects the list of files from a page and hit's download selected, then a post back happens to server and starts zipping on the server. This works great until we hit the timeout on the page ( which is default to 90 seconds ) and just returns the process to the page even though the backend process is still zipping. Is it possible to show the size of zip file when the file is being zipped instead of waiting till the end to provide the download link?
First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way:
protected void Application_Error(object sender, EventArgs e) { var err = Server.GetLastError(); if (err == null) return; err = err.GetBaseException(); var noObject = err as ObjectNotFoundException; if (noObject != null) HandleObjectNotFound(); var handled = noObject != null; if (!handled) Logger.Fatal("Unhandled exception has occured in application.", err); } private void HandleObjectNotFound() { Server.ClearError(); Response.Clear(); // new HttpExcepton(404, "Not Found"); // Throw or not to throw? Response.StatusCode = 404; Response.StatusDescription = "Not Found"; Response.StatusDescription = "Not Found"; Response.Write("The whole HTML body explaining whata 404 is??"); }
The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are:
1-What is the proper way of translating AnException into HTTP 404 response? 2- How does customErrors section work when handling exceptions in Application_Error? 3- Why throwing HttpException(404) renders (blank) page with success (200) status?
I am having problem redirecting error when error is http 500 or http 403 locally running this site there is no problem it gets redirected to my errorpage.aspx. But when deployed at server, it does not get .tried putting try and catch in page_load and in global.asax and I have set Application_Error to redirect to that page and also set <customErrors defaultRedirect to that page also
I am getting the following warnings on the Event Log for a Asp.Net WebSite running on IIS 7.
Exception information: Exception type: HttpException Exception message: Server cannot append header after HTTP headers have been sent. at System.Web.Hosting.ISAPIWorkerRequest.SendUnknownResponseHeader(String name, String value) [code]....
I tried to debug the WebSite but it just does not show in debugger. The web page which has got this issue contains the following.
Its a content page with a Master page.
It has a grid inside an UpdatePanel which is Triggered by a Timer.
On the specified time grid data is refreshed.
Everytime this happens we see a new warning in the EventLog.
---- 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.
I have a WCF client test harness where I'm using a "client message inspector" endpoint behavior to "pick off" raw requests and response messages going to and from a service and save them for later display in the UI.
This works great, except for the use case where invalid credentials are passed (Basic Authentication). The server returns an HTTP 401 along with a SOAP fault in the body containing details of what happened. I have no control over the service, so this behavior cannot be changed.
Because the HTTP 401 is returned as a WebException, my message inspector never fires and I can't get to the raw response. This exception eventually gets to the UI in the form a MessageSecurityException.
Is there any way to suppress this so the message inspector's AfterReceiveReply still fires? or is there somewhere else I can access the entire raw response?
The remote server returned an error: (407) Proxy Authentication Required.I get it when I use the GetReponse() method in WebRequest Dim request As WebRequest = WebRequest.Create(getNextURL()) Dim httpResponse As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)

I am creating one new silverlight webpart from VS Sharepoint 2010. If i am creating the silverlight application its asking for the sharepoint local site url, i gave the valid url but its showing the ["could not contact sharepoint server for list of document libraries. check your sharepoint URl"].
In my ASP.Net (2.0) Web Service implementation (The implementation class derives from
System.Web.Services.WebService with WebServiceBinding confirming to WsiProfiles.BasicProfile1_1 .
The SOAP response sent out by the Service has two elements missing :
1> The XML header itself : (<?xml version="1.0">)
2> The opening and closing Envelope tags with NameSpace ("<S:Envelope xmlns:S=http://schemas.xmlsoap.org/soap/envelope/>" and "</S:Envelope>" ).
This results in "breaking" of my client unless the above mentioned headers are inserted at the client end, and my intent is to avoid bypasses at the client end as far as popssible.Is this the default behavior ?

I have just installed IIS manager version 6.1 build 7600 and visual studio 2010 (latest additions of both).
I have followed all the instructions and given the correct permisions ect for IIS to work with my directory. I have a helloworld website that has worked via the localhost server many times, but almost hourly something happens to the settings in IIS and it starts throwing errors.
The current error copied below. Basically I am wondering a few things...
1. Why does my IIS constantly do something so that it works one minute and then it wont the next (this is with an identical helloworld.htm file so I know it is not something I am doing with the file that is messing it up).

I am currently trying to setup our website on a windows 2008 R2 64bit machine without much success. When I try to run the website I get the error detailed below. This only happens when I run the site under .NET 4. It works when I run it under .NET 2.
I have also tried going to a test aspx page to see what happens and it also give me the same error so it is obviously something to do with .NET 4 or the way I have it set up. I am thinking it might be a permissions thing but I am not sure what permissions should be set where. Please note this is the full version of .NET 4. The error I keep getting is:
HTTP Error 500.0 - Internal Server Error
An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.Detailed Error Information
Most likely causes: The module could not be found.IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
IIS was not able to process configuration for the Web site or application. The authenticated user does not have permission to use this DLL.

the same application is working fine in 32 bit machine of my colleague where as in my 64 bit machine I am getting the following error. I also tried by changing Target Platform of the web app, under Properties-->Build-->Platform Target: From X86 to X64, in fact I tried all 3.
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information:
More Information: This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.
[URL]I know how to remove the Server response header with an HTTP Module based on the link above. I just want to know why it is necessary to remove it this way.
