Description:
------------
A SOAPClient can be stuck in a redirect loop (and in some cases crash).
Other PHP functions have solved this by a default redirection limit of
20 redirects (maybe a php.ini setting) or a custom value of a stream
context -> http -> max_redirects.
I provide two examples, one where PHP crashes after ~200 requests and
one where it just loops forever.
Reproduce code:
---------------
redirection-loop.php:
<?php
header("Location: /redirection-loop.php");
?>
client code (crashes):
<?
$context = stream_context_create(
array('http' => array('max_redirects' => 3))
);
$soap = new SOAPClient(NULL,
array(
'uri' => 'foo',
'location' => 'http://example.com/redirection-loop.php',
'stream_context' => $context,
)
);
$soap->test();
?>
client code (never finishes):
<?
$soap = new SOAPClient(NULL,
array(
'uri' => 'foo',
'location' => 'http://example.com/redirection-loop.php'
)
);
$soap->test();
?>
Expected result:
----------------
I expect it to have a default limit of 20 but also respect the
max_requests value in the stream context. If the limit is reached I
would expect a SOAPFault with a similar error description as below.
When requesting the same file (redirection-loop.php) with
file_get_contents() you get a warning and a empty result is returned.
Warning: file_get_contents(http://example.com/redirection-loop.php):
failed to open stream: Redirection limit reached, aborting in Command
line code on line 1
Actual result:
--------------
This is what happens if you specify a stream_context and tries to make
it respect the max_requests (which is does not)...
