Error attempting to log into Redmine through IIS 7.5 Reverse Proxy
- by dneaster3
I am trying to set up Redmine as a subdirectory of our department's intranet site, and also to rebrand it as "Workflow" using IIS's URL Rewrite extension.
I have it "working" in that it will serve the page with all the correct rewrites in both the URL and the HTML code. However, when I try to submit a form (including logging in to redmine), IIS gives me one of the the following errors:
Your browser sent a request that this server could not understand.
or
The specified CGI application encountered an error and the server terminated the process.
Here's the setup:
Redmine installed on a local Windows XP machine using the Bitnami
all-in-one installer, which includes:
Apache 2
Ruby-on-Rails
MySQL
Redmine
Thin
Redmine runs locally at http:/localhost/redmine
Redmine runs over the intranet http:/146.18.236.xxx/redmine
Windows Server + IIS 7.5 serving up an ASP.NET intranet web application mydept.mycompany.com
IIS Extensions Url Rewrite and AAR installed

Any help that you can provide would be appreciated. I get the impression that I'm close adn that it is just one little setting here or there, but I can't seem to make it work.
