Re: [Soaplite-devel] bug: SOAP calls fail when folder with thesame name as the dispatch_to location

Thanks for the reply.

I am using SOAP::Lite under mod_perl, not CGI.

Ive tried altering my SOAP requests but I still get this intermittant
problem.  I have used your SOAP requests as models and the problem
continues.  I have further updated my SOAP requests to include a full =
URI as
per the SOAP spec.

I just tried it now and made two requests.  The first failed...the =
second
worked.  As you suggested I set 'MaxClients 1' in my httpd.conf.

As you can see the SOAP request does not change.

As I said before if I rename the folder (echo) to sometehing else =
everything
works perfectly.

This is typically an misconfigured SOAP client call, without namespace
and incorrect or empty URI in SOAPAction.

Same here.

Do you really store your Perl modules right on your web server directory
where your HTML is generated? This is a bad idea.

Test with "MaxClients 1" in your httpd.conf and it will fail straight.
You see the Apache children loading mod_perl resources during their
lifecycles.

Please provide your SOAP client calls and/or SOMs. In particular, the
SOAPAction header. It is impossible to verify without being able to
reproduce.

Here is my test scenario from what I could understand from your
description.

ll /var/www/cgi-bin/
