Hi Heiko, Well, I can try ... :-). Some thoughts here - hope this helps, but of course feel free to ask questions! 1) I have attached some code I put together to detect proxy information automatically (using WinHTTP, and in particular WinHttpGetProxyForUrl). It works with PAC files (at least it did for me ... :-)). I have also included some links in the code, to get more info on the Windows API's. Please excuse the poor coding though - I'm a HW guy, not a SW expert (not even close!). The slew of messages that I have put in the code are just FYI for now. These could be split to console output, or logging, or just removed. Whatever you prefer. BTW, I'm not sure how you use proxy in your code. At least with the PAC file that I go through, I get a response back of the format proxy.domain.net:8080;10.10.10.10:8080. We may need to parse this (again, just not sure how you use it). Also, I have not implemented asynchronous processing. It can be done, but not sure it buys much, as you really can't proceed until the proxy information is available. I also haven't modified the WinHTTP timeout. Again, this can be done if needed (but the response is typically quite quick). I agree with your targets - and one further comment ... auto-proxy detection should be done every time a connection attempt is to be started (i.e. even when reconnecting), agreed? 2) I can't say too much about automatic logon, but I have seen some example code on Microsoft's web site related to using fAutoLogonIfChallenged (more details starting from http://msdn.microsoft.com/en-us/library/aa383153(v=vs.85).aspx). They seem to show this automatically logging on the the proxy server (for HTTP requests), so it may be worth a try. Thoughts? Hope this helps you out! Take care,... Russell
