FastCgiWrapper ON doesn't work with FastCGI TCP

[atarkowska]

Reffering to the forum post ​https://www.openmicroscopy.org/community/viewtopic.php?f=5&t=7355#p13144 it looks like would be nice to add that to the doc. Our apache servers have that option turned off but would be nice to explain that in the doc.

FastCgiWrapper is designed for running CGI scripts as different system user, but this conflicts with the FastCGIExternalServer used in OMERO since it tells Apache to let OMERO handle everything via a network socket (the filepath passed to FastCGIExternalServer just acts as an identifier, and doesn't actually exist).

mod_fastcgi should really give an error if these two options are used together, instead of behaving unexpectedly ​http://thread.gmane.org/gmane.comp.web.fastcgi.devel/2699/focus=2148

Do you want me to take care of updating the docs?

Might as well include docs for #11723 in the same PR.

That would be great if you could update the doc.

My initial thought was to change nginx config as follow:

diff --git a/omero/sysadmins/unix/install-web.txt b/omero/sysadmins/unix/install-web.txt

                    fastcgi_param CONTENT_TYPE $content_type;

and in the end add note why FORCE_SCRIPT_NAME has to be set

Can you get a PR open for this asap please so we have time to review it ready for the release? Thanks very much.
