Hello
Just to answer my own question.
//How can I pass proxy information to Fedora/Apache HttpClient?
I've found some explanation on Apache HttpClient FAQ page and following
there is a patch which can resolve this problem. However, Fedora
behaviour in this case isn't how I was expected. Basically there is no
any URL parsing and all relative URLs are death and displayed page is
incomplete. I've just realize that in this case I should use (R)
datastream instead.

//I believe this is because our repository server is behind university
proxy/firewall; without user authentication. So I've added properties
such as http.proxyHost=wwwcache.our.domain http.proxyPort=8080 in
CATALINA/conf/catalina.properties file in order to propagate them in JVM
and Fedora software.

//Unfortunately this didn't help. I've started looking in source code,
and externally reference contend is accessed with WebClient.java class
which uses Apache Http Components library. In this class there is 20000
ms time out limit and I believe this should be enough to download and
process standard Google web page.
