Questions[soap](server)

I have a PHP-script which uses SoapClient that connects to an API and runs methods. It works on all the different servers I have run it on previously but when I tried it on a server I get the error:

SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://example.com?WSDL': failed to load external entity 'https://example.com?WSDL'

I have my thoughts that there is trouble with the server connecting to a https-domain. What server-library is Soap using in the background? Curl?

Thanks in advance!

I've a large F5 LTM load balancer environment I'm looking after which we are configuring to rate limit requests at a URI level. For human web users we are 302ing them to a busy page, but we also run web services and need to politely tell the soap client to go forth and procreate as well. Not knowing a whole heap about SOAP/XML responses I'm not clear on what we should tell the client. Will a very basic 500 reponse suffice or do we need to craft an legit SOAP response as well?

I installed php-soap on my Centos server from RPM file. Then I restarted httpd service but doesn't work SOAP client.

When I get:

There are SOAP options in php.ini file, there is soap.so in extension dir. But doesn't appear any SOAP option on phpinfo page. (Only soap.ini listed in ini files)

What can I do for enable SOAP extension?

Is there any plugin in Nagios that supports SOAP? I have a soap server and I would like to send requests from nagios. Is that possible?

I need to communicate with a httpS SOAP server on a different port than the standard 443. The client app doesn't work (because of restrictions) with different ports than the standard ones for HTTP and HTTPS

How can I setup my linux server running Apache to tunnel all these requests coming in at soap.domain.com to https://soapserver.otherdomain.com:1234/Service.asmx ?
