AJAX :: ISA Proxy Server Returning 407 For Request?
Feb 10, 2010
We are using 2 ISA proxy servers in front of our webserver and are getting intermittant Ajax errors in our application.
Our web logs indicate that there are 407 errors occurring during the requests.
When other users hit the webserver directly this issue does not occurr and this is also not an issue in IE8 but is in IE7.
The error dialog has Sys.WebForms.PageRequestManagerParserErrorException and the details say "error parsing near '<!DOCTYPE html P'

I am trying to make a web request programmatically. When i submit the request through the browser it seems to work fine but when i programmatically submit the request it comes back with this error message "Unable to connect to the remote server"
Below is the code i am using to executing the command,

I assume the reason why i am getting the error message is because the proxy server has not been set programmatically. Can somebody tell me how i can get the proxy server and set it programmatically?

I'm in .net4/VS2010/C#
In my code behind I would like to use Request.PathInfo in an onItemDataBound Event, but it's not returning anything.
These work: Request.Path, Request.FilePath, Request.RawUrl, etc.
Is there any reason why it wouldn't return anything?

I am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example. Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results.
Here is some code:
[Code]....
Now I am using the request method GET. This is in the actual request header from the original request.

How to write a webservice to call the proxy server through IIS webserver?

I have a website [URL]. Recently I found out that somebody has set up a reverse proxy with an almost identical url "www.website1.com" in front of my website.
I'm concerned of those users who came to my website through that reverse proxy. Their username and passwords might be logged when they login.
Is there a way for me to have my web server refuse reverse proxy?
For example, I've set up a reverse proxy using squid with the url "www.fakestackoverflow.com" in front of "www.stackoverflow.com". So whenever I type "www.fakestackoverflow.com" in my web browser address bar, I'll be redirected to "www.stackoverflow.com" by the reverse proxy. Then I notice the url in my address bar changed to "www.stackoverflow.com" indicating that I'm no longer going through the reverse proxy.
"www.stackoverflow.com" must've detected that I came to the website from another url and then redirected me to the website through the actual url.

I am in a situation where I need to get XML string of each product from server side on request, but only those tags that are added to XML at server side after the last client request. How can I determine at server side and return only newly added tags of XML of requested product to client so that only latest and relevant information could be shown at client side. And is there any way to save and keep on updating that XML data retrieved for each product on client side?

i only found websites that uses the XMLHTTP request to call an aspx page or what ever page ( make a request to a page that appears the piece of data in a div or so )but i have a question is it possible to use it to bind asp.net server controls Examples 1- bind a gridview or datalist from this XMLHTTP request 2- after click an edit button in a grid can i use XMLHTTP request to fill some text boxes and dropdowns and other asp.net server controls 3- can i use upload files using XMLHTTP request i want to know if this is possible or not because Ajax and update panels are very slow and affect the server and client performance is there another alternative if my senarios are imposible with XMLHTTP request where can i learn about this alternative if this possible where can i learn more about this XMLHTTP request with asp.net server side controls instead of ajax and updatepanel

I'm implementing a Google like search box in my asp.net application. Each keypress in the box sends an Ajax request to IIS webmethod that queries the txt and return matches - works pretty cool. However, on loading up activity (e.g. 300 users), I'm getting errors that my 100 Pooled connections are used up. Now I'm rethinking that perhaps opening/closing a db connection on each keystroke may be too much. How would one architect this differently, or insure that the connections are reclaimed really fast. I'm have the 'using' construct for connections to insure it is closed. The concern is GC may not be reclaiming them fast enough?
How would google handle such a large open/close cycle.

I have started having problems with our asp.net webform applications running behind a proxy since the user base have upgraded to IE7. Some postbacks seem to drop out and at times it is difficult to make controls on a page raise an event. It appears to be intermittant and I have been told there are issues around using IE7 behind a proxy with post requests. Is this the case and what are the options? Rewite in MVC? Does the issue of post requests behind a proxy remain in IE8?

We have an updatepanel in our site and there are a number of linkbuttons in it. Please note that the site works fine in all browsers without proxy the proxy changes the url from for instance [URL] to 0-[URL] it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is "Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; Tablet PC 2.0; InfoPath.1; .NET4.0C; .NET4.0E) Timestamp: Sun, 13 Mar 2011 20:38:58 UTC
Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
Line: 4674
Char: 21
Code: 0"
I have no idea what goes wrong here, it seems that IE can't parse the response?

For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?

our web application should be hosted under proxy server, for that we had to change our URL to be relative.
we changed all the url's but then we saw that web resources that are embeded in the .net dll's are being written to the page with absolute path, start with "/" for example:
[Code]....
how can we change it? how can we set the web resource to be relative like this "../webresource.axd"

(This is a more narrow question)
In my asp.net MVC action, I am looking if the ReturnUrl value is in the URL.
My Url looks like this:
[URL]
In my action, I am looking if that querystring value exists, and it is returning NULL?? How can this be?
The code:
if(Request.QueryString["ReturnUrl"] != null)
{
}
Tracing through the application, it is just skipping the if statement's body i.e. it is NULL.
How can this be explained?
[URL]

We have an issue when our web application runs under reverse proxy.
The reverse proxy change the URL for the website from for example: "http://TestWebApp/" to: "http://ProxyDomain/Test/" when it runs under reverse proxy which is mapped to "http://TestWebApp/" and rout requests to it.
This raise an issue of root relative paths (paths that start with "/" to be relative to the root of the web application i.e. "/Folder1/Test.aspx"). Generally all paths that need to be rendered to client we use ResolveClientUrl method and all is good.
When using Ajax controls and ScriptManager WebResource.axd paths are rendered in script tags as a relative url paths ("/WebResource.axd?blablabla") because the root under reverse proxy is the proxy domain itself the path is useless - the web resouce is not downloaded and the application break.
To fix this we tried to set a Response.Filter in OnPreRender event handler of our base page. In our custom filter we use Regex to search and replace all "/WebResource.axd" occurences with the resolved to client root path using the ResolveClientUrl method of the page. This works great and the web resources are downloaded to client.
But this is not the end of our troubles.
In Ajax requests the response output is fixed as described but when recieved at the client end it is not valid and the partial update fails with Sys.WebForms.PageRequestManagerParserErrorException.
It fails to parse the response because the rendered response have numbers that states the actual count of bytes per rendered component (which includes the script tags referencing the WebResource.axd). The client reciever validates the recieved response according to the numbers, but, our filter altered the response so the numbers are not correct and the response validation fails.
We can try and code a smart filter that parse the response and recalculate the numbers according to the ammount of paths fixed, but I hope there is an elegant and better solution for this.
