>Description:
When fetch is used with a HTTP_PROXY=XXX FTP_PROXY=XXX it does not always work as it should, And wget always works. 

But this is only true for only a few sites, most noteably https://helixcommunity.org

This is what I get from a distfile from https://helixcommunity.org

# fetch https://helixcommunity.org/download.php/1145/RealPlayer-10.0.4.750-20050401.i586.rpm

This is not always true, sites such as https://gna.org and others work great.


>How-To-Repeat:
Try to 'fetch' something with HTTP_PROXY set with squid or similar from
https://helixcommunity.org
