Hi,

As you know in an ajax request data is sent as parameters in the url e.g. page.php?param1=abc&param2=123

I'm having issues sending AJAX content as the server seems to be filtering/blocking it as it's too large, consequently my application fails. I have tested my application on a few webservers and on another web host and it works fine but on vlexofree it fails.

Basically I am sending some really innocuous JSON content via the URL string to a PHP page for processing. Originally I was URI encoding the parameters so the JSON data wouldn't get corrupted in transit. Now I am BASE64 encoding it so it's just a-z, 0-9 characters (even better).

Basically the URL request looks like this:

http://mydomain.tk/p...XJzTWlucyI6IiJ9

I'm guessing something in the XSS security software is blocking it as an attack? Maybe it's too long of a string I don't know. But it works fine on other web hosts so I don't know. Seems like an unnecessary protection if you ask me as it's really limiting what you can do with a web application.

Any ideas what could be going wrong?

I increased it to 2,048 characters. That should be more then enough.

Awesome thanks Eli. Got it working now.

You can use POST with ajax, with which the limit is several MB because it's not in the URL.
