Thanks, I'll look into that then, as other advantages too ...

One thing I just noticed.  I use 2 CMF sites under my root (One for each
canadian language). When this "hanging" occurs, one CMF site keeps working
(French, the less utilized one), while the other one "freezes" ...

How could this be ? I remember now having noticed this in the past.  Which
suggests that maybe this could also be a CMF problem ? Or maybe there are
various causes of "freezing" ... (In this case, httpd processes aren't
appearing all over the place like I described before ... maybe a similar
symptom with a different cause).

I'll try the apache+mod_rewrite+mod_proxy see if that helps though ...

thanks,
J.F.

We have seen similar behaviour (Zope 2.5.1, Solaris 2.5, Apache+FastCGI)
as long as we used FastCGI.

We switched from FastCGI to "mod_rewrite" with "[P]" rewrite rules
and the problem disappeared.
