Yes it's a URL...
but this is copied from howtoforge:
nano /etc/apache2/mods-available/fcgid.load
It looks like this:
LoadModule fcgid_module /usr/lib/apache2/modules/mod_fcgid.so
# add the following lines
<IfModule fcgid_module>
FcgidMaxRequestLen 51200000
</IfModule>
Save and reload Apache....
/etc/init.d/apache2 reload
works for all virtual hosts using fcgi.
I use ISPConfig3 and this corrected my issue with file uploads.
Still having problems with AbanteCart logs, no matter what settings I choose, just can't it to work

Cheers,
John
