[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.
View 3 RepliesI have defined this in the web.config of a subdirectory
<namespaces>
<remove namespace="App"/>
<add namespace="Tom"/>
</namespaces>
App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.
However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure
-Root Directory
--Default.master
--web.config (App is added in web.config)
--Tom Sub-diretory
---web.config (App is removed in web.config)
---Content page that uses Default.master (Here is the problem)
---Page without master (Works OK)
I am using a project that rewrites URL. I am not familiar with this code, but it works fine on IIS 6 and with VS2010. Problem begins when I need to deploy into IIS7.5 server. Seems like the rewrite doesn't work and the page doesn't fount after rewriting page.

How to modify the server value of response header through code behind using asp.net 2.0 with IIS6.0 server.
I have tried Response.Headers.Set("XYZ","ABC");
But it displays integrated pipeline error....
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 am using this code to download and its working well for me.But i cant understand the code.Can someone explain me this code to me please?
Response.AddHeader is used to add a new HTML header,but what is an HTML header all about?and the parameters i am passing within it as the name and value;what are they?
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.)
We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:
CryptographicException
Padding is invalid and cannot be removed.
When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:
Can I generate a machineKey via a tool on the server, or do I need to write code to do this?
Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)
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."
View 2 RepliesI have a site that dynamically loads website contents based on domain host name, served from IIS7. All of the domains share a cached collection of settings. The settings are being flushed from the cache on almost every page request, it seems. This is verified by logging the times at which the Cache value is null and reloaded from SQL. This codes works as expected on other servers and sites. Is it possible that ASP.NET Cache is being stored separately for each domain host name?
View 3 RepliesI need to add an expires header to my .less files in IIS7. Not quite sure how to do it.
View 2 RepliesThe application is hosted in Windows Server 2008 with IIS7.
I have a button that calls a new webpage (asp.net page, ext .aspx) that contains
Response.OutputStream.Write(blahblahblah) which then should prompt a download box to allow user to save an image.
Now the page basically creates a stream and then is supposed to output the stream to the user using Response.Outputstream.Write.
Then the user is supposed to be prompted to open or save the document. This works fine in Firefox but it does not work with IE7 or 8
Also this exact same code works with IIS6 on a Windows 2003 server.
So the only differences is the IIS6 and Windows 2003 Server to IIS7 and Windows 2008 Server.
And what happens is when I clicked the button, the page did pop up but disappear 1-2 seconds later without
prompting the download box to the user.
Here is the code that launches for Reference
//e.g file = 123424_43535.jpeg
FileInfo myFile = new FileInfo(Server.MapPath("mapImage/") + file;
using(var fs = myFile.Open(FileMode.Open, FileAccess.Read))
{
byte[] buffer;
int read;
buffer = new byte[(int)fs.Length];
Response.AddHeader("Content-Disposition", "attachment;filename=" + file);
Response.ContentType = "application/x-force-download";
Response.AddHeader("Connection", "Keep-Alive");
Response.AddHeader("Content-Length", fs.Length.ToString());
while((read = fs.Read(buffer, 0, buffer.Length)) > 0)
{
this.Response.OutputStream.Write(buffer, 0, read);
}
}
Response.End();
I have tried to replace Response.AddHeader with Response.AppendHeader, however the result is still the same. Also, I have tried to replace the Response.ContentType with application/octet-stream and image/jpeg, I also faced the same result.
Is there any setting/modification on server/code that I need to look on?
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.
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.

I have a simple web site with two pages. One displays a list of files, and the other streams a file when it's clicked in the list. All was fine in production for 6 months, but now I have to move the site to Windows 2008/IIS7. I have it mostly working, but the files don't open properly (in Firefox) because my content-type header is being ignored. On the production site (IIS6) the headers are (using Fiddler):
HTTP/1.1 200 OK
Date: Tue, 09 Feb 2010 16:00:51 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Content-Length: 236841
Cache-Control: no-cache, no-store
Pragma: no-cache
Expires: -1
Content-Type: application/octet-stream
but on the test IIS7 server I get:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 236841
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Fiddler also reports a protocol violation and says "Content-length mismatch: Response Header claimed 236841 bytes, but server sent 238378 bytes."
My code looks like this:

I am using a script manager for ASP.NET MVC to combine and compact CSS files and JavaScript files for pages on a website. For the most part this works as expected, however there are times (couple of times per week) when the HTTP handler responsible for returning the content returns an empty response and so pages load without any CSS - the HTML returns and the images load as well. When this happens, refreshing the page does not resolve the problem, while resetting IIS always resolves the problem. Also, without resetting IIS, after some time the problem stops.
Normally the script handler logs errors, however there are no errors logged during the issue. It seems as if the handler is never invoked. There are no failed request logs generated by IIS.
I monitored resource usage when this was happening and did not notice anything out of the ordinary. The web server is running IIS 7 and has low CPU usage. I increased some parameters in IIS settings regarding the number of allowable requests to process, the problem still exists though perhaps less frequent. The website receives about 1.5 million pageviews monthly.
I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is failing because of the way iis7 uses mime types, but I'm unsure how to fix it short of turning all compressio off.
View 1 RepliesI'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
We are working on a web application that creates more web applications.Each web application will have to get a Url Rewrite rule (URL REWRITE MODULE 2.0).As far as I know, there's no way to add such rules without modifying the web.config file (am I right??).So my plan was to work with multiple web.config partial files. One main .config file, and lots of .config files per application (every file will contain it's web application url rewrite rules).This way sounds a little bit messy, but I can't think of anything else, and suggestions will be welcomed.
View 1 RepliesI need to get the mime types in an IIS7 environment. They should be in:
<configuration>
<system.webServer>
<staticContent>
<mimeMap...
As I understand it, in IIS7 if I can get to it I should see both custom additions in my web.config as well as the mime types defined in the IIS manager at the machine level.
I don't understand how to get to this data. I have messed with the configurationmanager but I am not getting anywhere. I can get a section names system.webServer but I don't see any of the actual data as colleciton of properties or as xml.

View 1 RepliesI am trying to secure an application in IIS7 using .NET Authorization Rules.
By default, the web server allows all users access (which is inherited).
I have added, just for this one application directory, a deny all users command, as well as an allow command for specific users.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<authorization>
<allow users="myusername" />
<deny users="*" />
</authorization>
</system.web>
</configuration>
I have Windows Authentication enabled, and I can verify that without the line that my REMOTE_USER is MYDOMAINmyusername.
However, when I try to deny all users, I am prompted with the typical Windows domain username/password box. If I enter the username password, the prompt comes back up again 3 times until finally presenting me with a failure message. (I have also tried to no avail)
Looking in the event viewer, it appears as if my login using the username and pw is successful in the audit ... and to further that point, my account is not being locked out (which it would if I were failing to login over and over). So it's as if I am logging in, but the configuration is not seeing what I entered as matching my login.
Below is the message I see (even when connecting from the server using localhost):
**Access is denied.
Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL.
Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.**
I have a web.config file which is quite large in my current solution running on IIS7.
It's working perfect on my dev server however I encounter the error 0x80070032 "Config Error Cannot read configuration file because it exceeds the maximum file size"
My current solution uses a very large web.config file. The architecture of my CMS application requires a large number of configuration settings.
Is there some way to extend this size limit or can I split the web.config file down into smaller files?
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?
've programmatically created a listview, for displaying images. When you click on the download the ItemCommand is fired, and the browser sends the user the image as a binary response, using the following:
SPFile ImageIfile = spfolder.Files[ServerName];
byte[] bs = ImageIfile.OpenBinary();
string res = Page.Response.ContentType;
Page.Response.ContentType = "image/jpeg";
Page.Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(fileName))
Page.Response.BinaryWrite(bs);
Page.Response.End();
This works, exactly once. Then neither the download link, nor the DataPage paging controls
work until you refresh (Indeed any postbacks).
