What's more important, as little http requests as possible or splitting files for easy development?

I can't seem to get my head around this one. I'm using HttpWebRequest to try and send some data out to another site.

How to determine uniqueness of clients from http requests?

I notice that when http requests are made from clients through a proxy server, then the IP address of the requests is always that of the proxy. So if many clients from a huge corporation with a proxy server access a web site, I cannot tell if the requests are from unique clients or not. Is there any way to determine uniqueness of clien...

How to request an aborted HttpWebRequest again?

My objective is to retry an asynchronous HttpWebRequest when it fails. When I Abort() an HttpWebRequest, I cannot BeginGetResponse() again.

HttpWebRequest Cookie weirdness

I'm sure I must be doing something wrong. But can't for the life of me figure out what is going on.

How to send http request in asp.net without waiting for a response and without tying up resources

In an ASP.Net application, I need to send some data (urlEncodedUserInput) via http POST to an external server in response to user input, without holding up the page response.

Hi, I know this is a vague question, especially since I am not providing any code, but I am developing a .Net 2.0 application, and we have a WebRequest which posts data to an internally built API. The strange thing happens on our 3rd (and always the 3rd) subsequent request which fails at the GetRequestStream() method of the request. Th...
