[Tutor] Using jon.fcgi to speed up subsequent invocations

[Lloyd Kvam]

You need the apache fast-cgi module (You are using apache??)
### Section 2: 'Main' server configuration
#
<IfModule mod_fastcgi.c>

         # URIs that begin with /fcgi-bin/, are found in /var/www/fcgi-bin/
         Alias /fcgi-bin/ /var/www/fcgi-bin/

         # Anything in here is handled as a "dynamic" server if not defined as "static" or "external"
         <Directory /var/www/fcgi-bin/>
             SetHandler fastcgi-script
             Options +ExecCGI
         </Directory>

</IfModule>
I think this is fairly self explanatory.

I found Jon helpful in getting the regular cgi module to work.  My code (based
on his advice) looks like:

# somecgi.py
import cgi as stdcgi
import jon.cgi as joncgi

class Handler(joncgi.Handler):
	def process(self, req):
		fields = stdcgi.FieldStorage(fp=req.stdin, environ=req.environ)

There is a jonpy mailing list, but it gets a lot of spam.  The pyweb list
focuses on the more elaborate python web frameworks.

Hope this helps.  (Let me know if I left out critical info.)
