this could be as simple as allowing the execution of the scripr to
continue over 30secs, which tends to be a default.
If you are using the machine to do a lot of work, or if the machine is
busy doing other things, then it might take longer than 30secs, I was
thrown off saying this because you said it worked if you removed the
session line - but I wonder now what that meant.

In general, the way I would approach logging in to a site would be to
use the cURL library, and store the crendentials (crendentials that
you know work) for that connection inside a cookie file for the
duration.

Also [from a pm] you are using this to output close of play print
outs.
Why not open word, create a super looking (but not TOO complicated)
doc
with a certain format.
Put stars where the content should go
Make a page break where you need it
Save as RTF (which is open format and text)
(no images)
then save the RTF as a string, and add in the vars from the database,
cycling through until the last page
This works quickly and can be sent for download and archiving, and/or
saved to the server, works with linux and windows.
is quick and small zipped up.
Its harder than it sounds though, but looks fantastic.

I woudl say this is a simple timeout issue rather than what I
suspected - some kind of session or header issue, as you clearly
control the server on which the code is running, and so should know
what it accepts in terms of headers.

Use the cURL library to make the connection and you should be fine.
You can use methods such as yours but why reinvent the wheel here,
especially as there are great examplse online in the manual. (and if
you ever go SSl, it can carry on working with only minor revision)
