09/29/2026, 12:33 PMOne customer reverse proxy broke down after patching... seems to me that a POST request is not passed through to the backend web server, anyone else seeing the same? 13.1-64.24

09/29/2026, 12:34 PMWe are seeing similar with URL transformations.
Requests simply stop at Netscaler and time out. The backend connection is not even initiated. Nothing is logged.

09/29/2026, 12:43 PMI have already tried to disable WAF on System global settings and on the AAA config... I have also tailed ns.log for appfw events but there's nothing

09/29/2026, 12:49 PMI just got updated by another customer with the same issue.
We have now two customers that use URL transformations that are now having requests being hanging. In both cases we replaced url transform with multiple rewrite policies and it solved it.

Might be a known issue NSHELP-45430, maybe fixed in next release 14.1-74.11

10/06/2026, 1:51 PMI was told by the support that the issue is already fixed in 14.1-73.41 and 13.1-64.28, haven't found the time to test it yet, though

10/06/2026, 1:55 PMalthough, if one goes to the release notes docs.netscaler.com/us/en/…/citrix-adc-release-notes.html
"To view the release notes document for a specific build of release 14.1, click the corresponding link in the following table."
... what link?

Here is the direct link of the release notes for 13.1 64.28 :
<https://prod-docs.netscaler.com/en-us/updates.html?product=NetScaler%2520ADC%2520%28includes%2520NetScaler%2520Gateway%29&version=13.1&build=64.28>
You'll find the mention of "When a small POST, PUT, or PATCH body arrives in the same packet as the headers, the request might hang indefinitely instead of being forwarded to the backend." under the 'Fixed Issues' tab and 'NetScaler Web App Firewall' module.4 Views
