F5 10 LTM APM with XenApp CloudGateway

I would start by trying out the script that is posted on Devcentral to recreate your xml monitor; a link with instructions on how to use the script are located on page 31 of our iApp deployment guide: http://www.f5.com/pdf/deployment-guides/xenapp-xendesktop-iapp-dg.pdf. The refererenced script should work fine on v10.

 

 

Hopefully that resolves the issue, if not then the best way to see why the post is not working is to capture traffic on your server to see how the server is responding to the xml monitor post.
