Under Apache  the limit is a configurable value  LimitRequestLine  Change this value to something larger than its default of 8190 if you want to support a longer request URI  The value is in  etc apache2 apache2 conf  If not  add a new line  LimitRequestLine 10000  under AccessFileName  htaccess    However  note that if you re actually running into this limit  you are probably abusing GET to begin with  You should use POST to transmit this sort of data -- especially since you even concede that you re using it to update values  If you check the link above  you ll notice that Apache even says  Under normal conditions  the value should not be changed from the default

Based on John s answer  I changed the GET request to a POST request  It works  without having to change the server configuration  So I went looking how to implement this  The following pages were helpful   jQuery Ajax POST example with PHP  Note the sanitize posted data remark  and  http   www openjs com articles ajax xmlhttp using post php  Basically  the difference is that the GET request has the url and parameters in one string and then sends null   http open  GET   url     params  true   http send null     whereas the POST request sends the url and the parameters in separate commands   http open  POST   url  true   http send params     Here is a working example   ajaxPOST html    lt html gt   lt head gt   lt script type  text javascript  gt      function ajaxPOSTTest             try                  Opera 8 0   Firefox  Safari             ajaxPOSTTestRequest   new XMLHttpRequest              catch  e                   Internet Explorer Browsers             try                   ajaxPOSTTestRequest   new ActiveXObject  Msxml2 XMLHTTP                  catch  e                    try                       ajaxPOSTTestRequest   new ActiveXObject  Microsoft XMLHTTP                      catch  e                           Something went wrong                     alert  Your browser broke                         return false                                                     ajaxPOSTTestRequest onreadystatechange   ajaxCalled POSTTest          var url    ajaxPOST php           var params    lorem ipsum amp name binny           ajaxPOSTTestRequest open  POST   url  true           ajaxPOSTTestRequest setRequestHeader  Content-type    application x-www-form-urlencoded            ajaxPOSTTestRequest send params                Create a function that will receive data sent from the server     function ajaxCalled POSTTest             if  ajaxPOSTTestRequest readyState    4                document getElementById  output   innerHTML   ajaxPOSTTestRequest responseText                   lt  script gt    lt  head gt   lt body gt       lt button onclick  ajaxPOSTTest    gt ajax POST Test lt  button gt       lt div id  output  gt  lt  div gt   lt  body gt   lt  html gt    ajaxPOST php    lt  php   lorem   POST  lorem    print  lorem   lt br gt       gt    I just sent over 12 000 characters without any problems

I have a simple workaround    Suppose your URI has a string stringdata that is too long  You can simply break it into a number of parts depending on the limits of your server  Then submit the first one  in my case to write a file  Then submit the next ones to append to previously added data
