SOS topology icons are not loading behind a reverse proxy

[yoho]

After running a trace with HTTPfox behind my browser, I found out the reason why I wasn't able to see the icons in the "topology" view.

Icons in this view are referenced as relative to the "root" of the URL server. For instance,

/static/app/sos/images/Forwarder_orange.png

Problem is that this URL is not caught up by the reverse proxy as belonging to splunk. Indeed, I had to define the "root_endpoint" parameter in web.conf and my reverse proxy is relying on it. Eventually, I obtain a 404 HTTP error message from the reverse proxy.

Without a reverse proxy, Splunk is nice and redirects the previous URL to "http://$splunk_server/[$splunk_root/]en-US/static/app/sos/images/Forwarder_orange.png" but unfortunately my browser is not talking to splunk directly so won't get redirected.

By the way (but probably out of scope for SoS), the redirection appears to be hard-coded to "en-US", even if your locale in the URL was "en-GB".

It is a minor defect in the app. Supporting custom root endpoints in apps is difficult and little issues like this tend to get missed. I found the issue in the code and I'll reach out to the developer wrote the app so we can get it fixed.

Still doesn't appear to be fixed in the latest version of SoS 😞

Is there a work-around without a patch/release? I noticed a problem with GoogleMap app that seems very similar to this one, as described here:

Any help on my problem?

Thanks,

BTW: the developers of SOS acknowledged the issue and are fixing it.
