--- Comment #1 from François Gouget fgouget@codeweavers.com --- Ideally no Perl script should not get involved for sending static stuff such s log files and screenshots. That's the job of Web servers and they can do that much more efficiently.
Once / if these file are no longer sent through perl scripts then this issue becomes moot. See also bug 47900.
