Apache::Registry executing scripts multiple times

Hi All,
Please forgive me if the answer is in the docs, I looked without success.
I have a very simple index_test.pl script which appears to get called by Apache::Registry
multiple times. I have tested in single server mode (httpd -X) and still get the same
results. The output is correct but the error_log shows multiple calls from the
Apache::Registry module. While this simple program appears to get called 5 times
our big one was only getting called twice, however, that did have a very noticeable
effect on response time.

We have also removed the Apache::Reload module without effect.

Any ideas, pointers or help appreciated

Dave

I don't see anything in what you've shown us here that would explain
this behavior. I think the problem is in the rest of your httpd.conf,
or your proxy/load-balancer, or your test client.

our ? shouldn't that be my ? our makes that variable a package global,
so it will stick around between requests, just like $some::package::name
would.

Re: Apache::Registry executing scripts multiple times [In reply to]

Thanks to all who responded.

It is a development setup so no proxy or load balancer in the mix
I could have sworn I had tested the behaviour in other clients, we use Opera,
so I took the Apache configuration back to bare bones and still had the issue.

Testing with Firefox showed the expected (single call) behaviour.

Fsck, I hate browsers.

Anyway, now to test a simple CGI call and see if the Opera strangeness continues

Thank once again for your help

Dave
