Access Spectrum WebClient throgh reverse proxy

Issue/Introduction

We have a requirement to allow web access from a customer network to our OneClick server via WebClient. Due to security policies we need to implement an application layer gateway between the customer network and our OneClick server, which will work as a reverse proxy for certain web applications - one of them being OneClick. The use of java is also restricted so we cannot use the java client.

Accessing the WebClient through a reverse proxy causes infinite display of the "Initializing..." message, which blocks all UI access indefinitely.

Why can we not use the OneClick webClient via reverse proxy?

Environment

Spectrum 10.2.3 and below.

Cause

This is caused by underscores in the header not being accepted and can be worked around via Apache or ngix
