Maximum HTTP request length
Maximum supported length for a HTTP GET Request in IE is 2048. On the other hand a HTTP POST request does not almost have any restrictions on the length as it supports up to 2GB size of text for the content length. The primary usage of a GET request is to fetch data from the web server while the POST is used to submit data.
