[Mapserver-users] WMS Client Problem

[bartvde at xs4all.nl]

Hi Stefan,

I had the exact same problem (and still have, because we have changed
things in the firewall/proxy to solve this).

I think you need to recompile Mapserver and libcurl to have it going
through the proxy. Not a totally trivial task.

I think it would be a nice enhancement to Mapserver if we could specify in
the MAP file whether or not the WMS client needs to go through a proxy and
then the address/URL of the proxy. Also some kind of authentication
support for the WMS client would be nice.

Best regards,
Bart
