http:request returns {error, session_remotly_closed}

[Soren Gronvald]

Thanks for replies. 

I can make it work with ibrowse, but I still have the
problem with http:request even when I do asynch. 

I found an earlier discussion from may 2005 about a
similar problem:

Any one knows if this fix got into open source erlang,
and what it was?
