Hi everyone,

I am encountering what appears to be a timeout problem using a PHP
soap client to connect to a VB.net soap server. I cannot provide the
WSDL as it is only available for internal use -- if this is essential
I can create an equivalent mockup.

I'm running an Apache 1.3 webserver. I call the script via a web
browser.

php.ini has the following pertinent settings:

default_socket_timeout = 120
max_execution_time = 60
memory_limit = 20M

A simple equivalent to the script looks like:

<?php

$soapClient = new SoapClient('http://www.example.com/path/to.wsdl',
array('connection_timeout' => 120));

try {
$soapClient->WaitBeforeResponse(500);
} catch(Exception $e) {
echo $e->getMessage();
}

?>

The server method WaitBeforeResponse sleeps for the time provided, and
then returns 'Hello, World!'.

Consistently, after 15 seconds the Soap Client throws the following
exception:

"Error Fetching http headers"

Nowhere in any of my configuration files do I see the number '15' come
up. If WaitBeforeResponse(5) is called, it returns 'Hello, World!'
correctly.

Is anyone aware of a configuration directive I am missing that would
explain the consistent 15 second timeout? When executed directly on
the soap server (.NET provides built in WSDL execution functionality)
calls can take as long as they want, and still ultimately produce a
result.
