Socks Proxy for HttpWebRequest

.net proxy httpwebrequest socks

According to my research whilst trying to solve this problem, it turns out that the .Net WebProxy class does not support Socks proxies - a tad annoying. I also can't seem to find any code or information which explains how to implement Socks 4/5 support via a class which can easily be used with HttpWebRequest (the Proxy property, to be exact).

I've found limited information via google on how I could do this. One suggestion involves changing internet explorer proxy settings - something I'd rather not do.

Does anyone know of anything which could do the job or have any suggestions? Any help would be much appreciated.

I tried numerous .Net libraries which claimed to support Socks4/5 but found many of them just did not work or would error trying to connect to proxies I knew were functioning.

I've ended up using Chilkat Software's Sock/SSL component which seems to work well for me even if I do have to manually construct the HTTP requests instead of using HttpWebRequest as I would have liked.

  • Update note: Chilkat.Http (similar to the HttpWebRequest class) does inherently have support for SOCKS proxies. So don't spend time trying to code your own HTTP requests as I did; just use the Chilkat.Http.SocksHostname, Chilkat.Http.SocksPort and Chilkat.Http.SocksVersion properties.
