POST data not being sent when sending large strings.

[Jumaro]

My server runs PHP 4.3 and I'm having a problem where when I try to to submit a long string, about 3500+ characters in length, using the post method, the $_POST array node that is supposed to hold that string is dropped for some reason. I don't get any error messages and other $_POST elements return successfully.

I checked my post_max_size and it is at the default 8mb and the string I'm trying to submit is no where near that size obviously.

And when I decrease the size of the string it is returned successfully.

My server runs PHP 4.3

Any help would appreciated

Can you post your code?

The string that I'm trying to post is dynamically generated here it is the firs part is junk just to increase the string size.

var XMLstrings = '<form><divsize><width>450</width><height>650</height></divsize><text><value>%26lt%3Bh1

here I'm using mootool ajax class here to submit the sting, I tried just creating a hidden field with the sting but it didn't work either

            var thisrequest = new Ajax(yoururl, {
                method: 'post',
                data: 'xmltotransform='+XMLstrings,
                onComplete: creation_msg
            }).request();    
       }

php code in the processing page

[PHP]<?php print_r($POST);?>[/PHP]

and $_POST is empty.

I should point out that I am using firebug to depug and shows that it is submitting the full string but there is no response.
