Dispatcher URI Length Limitation?

[gbrauser]

Is there a limitation in the dispatcher in terms of the length of URIs that it handles?  We have run into an issue with long (but not really that long - say over 256 characters) that return a 403.  But if we access the same resource directly on the pub server, it works fine (i.e., it renders the content as expected).  We are using Apache as the web server - I don't think it is an Apache issue.

To my knowledge there is no dispatcher limitation. I have run files with some very long names through dispatcher (much longer than 256 characters). 

What version dispatcher, what version of Apache, and what OS.
