URLs containing colon: Win32 vs. Linux

[Jeff Trawick]

Does anybody have a quick answer, like "can't have colon anywhere in uri 
path" or  "we're busted" or something else?

URL is http://127.0.0.1:8080/dobedobedo;session=0:0

dobedobedo doesn't really exist

Apache 2.0.47 on Win32:
 -> 403 (no reason logged)
Apache 2.0.47 on Linux:
 -> 404
I'll try to figure out which filepath operation is blowing and make sure 
we log something for such errors and see what we should be doing.
