PROBLEM:

The file_get_contents() function returns the wrong url.

OVERVIEW:

If you point your browser to "http://finance.yahoo.com/q/op?s=A" you will get the first set of options (in this case April 2008) for Agilent. If you point it to "http://finance.yahoo.com/q/op?s=A&m=2008-05" you will get the second set (in this case May 2008).

HOWEVER:

If you use the file_get_contents() function you will get the first set regardless of which url you use. It ignores the "&m=2008-05".



Reproduce code:
---------------
$url = "http://finance.yahoo.com/q/op?s=A&m=2008-05";
$content = file_get_contents($url);


Expected result:
----------------
I expected the May 2008 options page.

Actual result:
--------------
I got the April 2008 options page.
