sounds good. did some tests with mod_fcgid. cpu-load is higher then using
mod_php but not as high as expected.
is this the way how it the big ones do?
is it possible to show your config?
there is one sentences in the docs which sounds strange
###
Warning
Currently, only one FastCGI application of any type (AAA or handler) can be
used for a particular request URI. Otherwise, the wrong FastCGI application
may be invoked for one or more phases of request processing.
###
this means that only on fcgid-script per location is possible? i would like
to have .php4 files bind to a php4-wrapper and .php5 files bind to a
php5-wrapper in same directory. i did some tests but could not confirm or
decline.
Thanks,
Hajo

Well it doesn't seem to work that way, see this-

I wouldn't put that in your /cgi-bin if I were you, or anywhere it could
be invoked directly. It looks unsafe.

If I understood your question properly, you're asking that
/htdocs/a.php is one fastcgi app and /htdocs/b.php is another.
If you want it this way, then you will have to add the shebang (#!)
line to all of your scripts before <?php starts, which is not a viable
solution if you have many php scripts which directly interact with the
public.
I don't use that method, see my config below. .php is processed
without any shebang stuff.
FcgidMaxProcesses 100
FcgidMaxProcessesPerClass 50
FcgidFixPathInfo 1
FcgidPassHeader HTTP_AUTHORIZATION
FcgidMaxRequestsPerProcess 100
FcgidOutputBufferSize 1048576
FcgidProcessLifeTime 60
FcgidMinProcessesPerClass 0
FcgidIOTimeout 120
ExpiresActive On
ExpiresDefault "access plus 1 month"
# This config below ensures that php is processed w/o presence of shebang line
DirectoryIndex index.html index.php
AddType text/html .php
AddHandler php-fastcgi .php
Action php-fastcgi /cgi-bin/php.fcgi
<FilesMatch "\.php$">
Options +ExecCGI
ExpiresActive Off
</FilesMatch>
And the source code for /cgi-bin/php.fcgi:
#!/bin/bash
export PHPRC=/usr/local/etc/php PHP_FCGI_CHILDREN=0
exec /usr/local/bin/php-cgi $@

Depends on what *you* mean by "location". It says only one fcgid
application per *uri*.

That should work fine. A URI ending in ".php4" is not the same URI as
one ending in ".php5".
