Using IE browser the sharepoint webpage will load partially and multiple browser refresh have to be made to load the contents completely. However, other browsers like Chrome, Firefox is able to load the contents successfully.

Refer the 2 screenshot which indicates the difference in HTTP Header size. Increase the MaxHTTPHeader Length in HTTP Profile and bind to the respective Virtual Server (VIP).

Working on Chrome browser:-

Not-Working on IE browser:-

Problem Cause

MaxHeaderLength: Number of bytes to be queued to look for complete header before returning error. If complete header is not obtained after queuing these many bytes, request will be marked as invalid and no L7 processing will be done for that TCP connection.IE browser send additional Information / parameters in the Negotiate HTTP Data as compared to the other browsers like Chrome and Firefox. Similarly on Netscaler default limit of MaxHTTPHeader length is 24820bytes (Min = 2048, Max = 61440) this limit has been reached and hence Netscaler is blocking by sending RST.
