HTTP Proxy connection
Hi, I have problem with downloading work for WCG.
I'm using Boinc 6.4.5 for Linux on Ubuntu Jaunty. I'm connecting trough Squid Http Proxy. I'm in Seti and WCG projects. With Seti I don't have any problems to download units. Here are logs:

Re: HTTP Proxy connection
Looking at your stats, is this a new problem to a previously functioning client doing WCG work?

Most proxy information is found in help article: http://www.worldcommunitygrid.org/help/viewSearch.do?searchString=proxy

Your log has this piece "invalid distance too far back", which I cannot find as having been posted before on these forums. This popped up with oogle:

http://newsgroups.derkeiler.com/Archive/Comp/...ion/2006-01/msg00204.html

WCG is different from all other projects we know. SSL connection is used, which is sometimes combined with proxy an issue.

Re: HTTP Proxy connection
Maybe it's just a question of http 1.0. See this thread:
