Limit on POST data size

[Coomkeen]

Hi All,

I have a problem that no-one seems to be able to solve.
On a site I run we have an admin area with a page to send our newsletter.
It's the usual html form with a textarea, and various radio buttons for testing options etc.
The newsletter editor pastes his html into the textarea, (which is called 'bdy' meaning the body of the newsletter) and hits the 'send' button.

On hitting the 'send' button it uses the <action= ???> to send to a handler.php file.
That reads the data sent using $_POST[bdy], and adds an unsubscribe link at the end, and either sends to one of the admin people (me included) as a test, or to all the subscribers getting their email addresses from a database.

This worked fine up to last October, when we discovered it didn't like data bigger than about 60k.
That was fixed then by someone on the helpdesk who said, I think, that it was to do with mod_security.
All has been working fine since, until yesterday.

Now it's back to not passing data bigger than 60k.
A chap on the helpdesk says he can confirm that is the case, but hasn't got any solution to it. He says mod_security has been disabled, and I've already got :

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

in the .htaccess file.

Something has changed, but what, and how to fix it?

ALL ideas welcome.
