[MapServer-users] cgi/fcgi mapcache problem

[Richard Greenwood]

I have been running mapcache as an Apache module. I'm now trying to get the
same configuration running as a FastCGI process. But making a CGI or FCGI
request I get the error message "missing a service". I have the mapcache
binary installed in the Ubuntu cgi-bin directory. The full urls are below,
but the only change in the urls is from /mapcache/? to /cgi-bin/mapcache?
or /cgi-bin/mapcache.fcgi? The query string is the same. The query string
contains a SERVICE key.

With the FastCGI I can see the mapcache.fcgi process is still there for a
while as I would expect. The Apache error log shows a warning with the same
"missing a service" and a response code of 404. But the 404 is clearly
being generated by the mapcache process, not Apache.

This is on Ubuntu 22.02 with standard repo install of mapcache 1.12. I
tried it on two different computers, same problem. One computer did not
have the Apache module installed so it's not a conflict between the module
and the CGI. I tried changing the WMS version and a few other random things.

Apache module, works:

FastCGI, error:

CGI, same error:
