serializing access to a resource in my mod_perl PerlHandler

[John Kelly]

Hi,

this is an oldbie question - i used to know something about mod_perl but haven't used it for so
so long I've forgotten it all :)

a mod_perl script i wrote quite some time ago has recently had
increased "traffic". this has shown up a problem (i think) with
serialization of resource in the "back-end" system that my mod_perl routine provides
a wrapper for.
In the short-term, while I'm investigating the problem I'd like
quickly to modify something so all requests through the PerlHandler
which processes the content are serialized.
So, is there a configuration directive which can do this without
modification to the script itself ? If not, how can i implement some
form of serialization within the handler ?

thanks in advance
John
