Problem this snippet solves:

This TMSH script quickly and easily creates a monitor for Citrix XenApp or XenDesktop on an LTM. Instructions for importing and executing this TMSH script are found in the F5 deployment guide. The script takes three inputs, username, password and appname and then automatically calculates the POST Content-Length to create a customized, specialized monitor for your Citrix environment.
