Hi everybody,

I am having a problem using libcurl in my Ruby app (Curb gem binds directly
to libcurl). Specifically libcurl can't follow a weird redirect served by a
web server. Server Location header "Location:
http://www.officedepot.com;jsessionid=0000EXsMRFMF5kwJo26qgOif31d:13ddq0tfm"
doesn't look RFC complaint to me. For whatever reason jsessionid gets added
to the end of new location.
Below is curl command to reproduce the problem and full curl output.
Versions tried: 7.19 and 7.21. OS: Ubuntu 10.04 and 11.04. Somehow
browsers can handle this redirect. I even tried using browser's user-agent
and it has no effect on server response. I just assume browsers are more
permissive. libcurl source code in master on github didn't trigger any
solutions to me. So here is my question if there is a way to work around
this problem?

Thanks a lot in advance for your help,
-Alex
