Issue/Introduction

When using Open Workbench via reverse proxy, Save and save As function might fail.

Checking the access.log files we might find the session ID is missing on the POST request:

Access log without reverse proxy     There is session id at the end of URL.
xx.xx.xx.xx|[07Aug/2018:18:16:15 +0900]POST /niku/app?buildVersion=800
&post=true&action=schedulers.GetSavePrecheckRequest&externalSource=CA+PPM+Workbench
&version=117440512 HTTP/1.1|200|44|46|5903078__ED49B438-0A57-4084-90F8-A4BEA66F8AB9

&version=117440512 HTTP/1.1|200|59|18|

Cause

PPM needs to use the same session (Sticky Session) in a multi server environment.
Open Workbench also requires Sticky Session.

Environment

All environment

Resolution

Configure Reverse proxy to enable Sticky Session.
