Some really good news for anyone interested in WSGI is in Diary for titus: WSGI, Quixote, SCGI, QWIP, and SWAP.
Thanks to Titus Brown we now have 2 great new options.
First a new WSGI server using SCGI from the Quixote project and SWAP, the "SCGI-WSGI application p(something)". That may be the best performing WSGI server to date as it uses mod_scgi to talk to apache.
Second a new WSGI framework using QWIP, the "Quixote-WSGI interface p(something)" we should now be able to run any quixote application on any wsgi server.
I have not yet tested any of this but it is very exciting news.
Many thanks Titus.
