<font face="Times New Roman, Times, serif">Hi everybody,<br>
<br>
I've been trying to setup a cascading mapserver using the itasca demo
files but I can't get the cascading server to work ok.<br>
<br>
If I connect directly to the originating WMS server, everything comes
up ok (both GetCapabilities and GetMap).<br>
<br>
If I connect through the cascading WMS server, I can get the
Capabilities XML, but all GetMap requests come up with a 500 error.  In
the Apache log I can see the following errors:<br>
<br>
[Tue Jan 20 10:17:57 2004] [error] [client 127.0.0.1] Premature end of
script headers: mapserv.exe<br>
[Tue Jan 20 10:17:57 2004] [error] [client 127.0.0.1] ERROR 4:
`path/to/wmscascade/Images/107461187731640.img.tmp' not recognised as a
supported file format.<br>
<br>
Here is my mapfile for the cascading server:<br>

And finally, the request URL:<br>

<br>
Other detail that might be interesting:  I get nothing in the mapserver
log file that I specified (/wmscascade/cascade.log).<br>
<br>
Does anybody have any clue?<br>
<br>
Thanks in advance,<br>
