Windows FastCGI alternative

[cxallan]

An alternative for the FastCGI + Apache/nginx/lighttpd on UNIX based platforms should be investigated for Windows. Options include:

• ​http://sourceforge.net/apps/trac/pyisapie
• ​http://code.google.com/p/isapi-wsgi/
• others...

[cxallan]

pyisapie is a complete wash. Largely unsupported. Made good progress with isapi-wsgi on IIS7 (Windows Vista Enterprise), am hitting the following error:

Example install script for ISAPI WSGI on IIS

[cxallan]

Adding Josh to the CC line so we can try and work out a solution for the temporary directory resolution when running under the "NETWORK SERVICE" IIS user.

With this Django bug (​http://code.djangoproject.com/ticket/9084) we need to use the "cache" based session engine.

[cxallan]

(In [8510]) Added OMERO.web IIS installation script (requires ISAPI-WSGI; ​http://code.google.com/p/isapi-wsgi/) (See #3194)

(In [8511]) Added a warning message for those who attempt to use the FastCGI workers on Windows. (See #3194)
