Add context url to powerbi endpoint

[jcaroe]

Hello everyone,

I asked a similar question a couple months ago but after testing out some options we are still on an empasse.

Basically what we are trying to achieve is add a context url to each Report Server - Power BI virtual directory. Those are:
/Reports
/ReportServer
/powerbi

Through the use of an apache server, we managed to add the context we need in front of /Reports and /Reportserver, re-writing urls to /omr/Reports and /omr/ReportServer. 
We still have problems with the third virtual directory, which is /powerbi. What happens when you navigate to any dashboard inside a Report Server is that internally, the Web Page of the Report Server calls /powerbi endpoints to retrieve the corresponding data. The problem is that we need that endpoint to be rewritten to /omr/powerbi, but we cant do that server side. We need to have a way to change it in the fetch operation, when the request is sent.

Is there any possibility to do this?

Hi @jcaroe ,
You are not doing anything wrong here. Its just that Power BI Report Server does not officially support hosting behind a sub-path  like /omr . It is designed to run at the root of a domain.
Best practice is to host it at the root of a dedicated subdomain.
If you still need help, you can open a Support ticket.

Hi @jcaroe ,

Power BI Report Server does not support adding a custom context path  to the default URLs (/Reports,/Report Server)  and this includes the /Powerbi virtual directory.

Altering the built-in virtual directories themselves is not supported through any PBIRS configuration options.

To have everything under a prefix like /omr, you’ll need to handle that in your proxy layer, not PBIRS.
However, you can try to add a reverse proxy route for /powerbi.

This documentation provides step by side guide to configure reverse Proxy

Unfortunately, even with reverse proxying, the problem for us still remains, because the FE of Power BI Report Server still sends requests to https://hostname/powerbi -> the "hostname" is a proxy server which only understand /omr paths, and powerbi is rejected.

Thank you for your time.
