Max size of URL parameters in GET

Question

I am accessing a PHP server using REST  all data is passed in a GET request as URL parameters  One of the parameters arrives at the server in the query string  but it is not in the  GET global  But shortening the parameter  the cutoff seems to be around 512 characters  lets it through   Assuming I have diagnosed the problem correctly  is there a way to change this maximum size  I have not found any explanation in the documentation  not even a mention of this limit  This is on Debian squeeze   Apache 2 2 16   PHP 5 3 3

Ok  it seems that some versions of PHP have a limitation of length of GET params      Please note that PHP setups with the suhosin patch installed will have   a default limit of 512 characters for get parameters  Although bad   practice  most browsers  including IE  supports URLs up to around 2000   characters  while Apache has a default of 8000        To add support for long parameters with suhosin  add   suhosin get max value length    lt limit gt  in php ini   Source  http   www php net manual en reserved variables get php 101469
