in reply to Re: HTTP::Proxy : changing the URI
in thread HTTP::Proxy : changing the URI

sorry i reply just now... i was pretty tired yesterday evening, so i didn't touch a pc after work ;-)

i showed you a bad example of my code, the working code does use the HTTP::Proxy::HeaderFilter::simple. (otherwise the filter doesn't work; like you also mentioned). i've added the working code to end of this reply.
the $message->$headers->header should have been $message->header (when using HTTP::Proxy::HeaderFilter::simple), and that methods sets or gets a header variable. about the patch: yeah, I thought it was something like that, but is the error really coming from HTTP::Proxy?

anyhow, thanx a bunch for the tips, the patch-tip is probably going to be the most successful one... but i'll keep you posted (btw: we already arranged that the product that's supposed to use this proxy, will use it as a proxy (so it will make "correct" requests). so actually my problem is solved, but I still want to see if this idea would work.. it would be cool, no?)
