Large file upload failures

September 21, 2020

Contributed by:

When you encounter large file upload failures, ensure that you check the following:

– Misconfigured application firewall postbody limit – Enabled file upload scanning leading to increased processing time. – Hitting system limits.

For payloads greater than 20 MB, Citrix recommends you to enable streaming on the application firewall profile. Also, you must ensure the back-end server supports chunked requests before enabling streaming.

Since release 11.0, the streaming flag can be enabled on per profile basis to avoid buffering by executing the following command:

set appfw profile <profile name> -streaming on
