Parsing form input in a BaseHTTPServer

[Ron Garret]

I'm write a web server using BaseHTTPServer.  It can't be a CGI because 
it has to do some weird server-push stuff as database updates come in.  
But I still need to process form inputs as if it were a CGI.  But the 
cgi module only works in a CGI environment.  Is there something with the 
equivalent functionality of cgi.FieldStorage for parsing form input in a 
non-CGI environment such as a BaseHTTPServer?  I looked at the cgi 
module code but it looked like it was pretty heavily intertwingled with 
the CGI environment variables.

Thanks,
