Item11491: FCGI has de facto file upload limit - add note in documentation for fix.

See Support.Question1022 for details. I don't really understand the technical details or how it should be presented in the docs, however the fix is to add the follow to the apache config file:

<IfModule mod_fcgid.c>
# to get around upload errors when uploading images increase the MaxRequestLen size to 15MB
  MaxRequestLen 15728640

</IfModule>

I suppose one should adjust the value to correspond roughly to ATTACHFILESIZELIMIT preference setting. I don't know how it might affect performance making this value higher.

Perhaps this could also be incorporated into the ApacheConfigGenerator options for fcgi.

Here's documentation of the fcgi MaxRequestLen setting which mentions this issue:

• http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html#fcgidmaxrequestlen

Updated ApacheConfigGenerator to document this parameter & relationship to file size. Also added a note to FastCGIEngineContrib documenting the requirement.
