IIS 7.5 URL rewrite is dropping parts of URLs with a tilde (~)

Question

I'm trying to run a reverse proxy through to a website running locally through IIS to get SSL functioning. I've got all my rules set up so that I can see 90% of the site perfectly. The application is Atlassian's Crucible, but I think my issue is more generic than that.

The bad request has the following format (with sanitized names and paths)

https://bar.foo.com/crucible/cru/CR-4/edit-changelog/~author%3Dtheauthor%2520%253Ctheauthor%254040foo.com%253E/repository/

It appears that the URL re-write is dropping everything after the ~ character in the request.

For my inbound rewrite rule I've tried

crucible(.*)
^crucible(.*)
^/crucible(.*)
^/crucible(.*)$

And about a dozen other variations. I've also done this with the 'apply query string' box both checked and unchecked.

Answer 1

I've finally figured out a way to get the application to work correctly. The correct UR is

crucible(.*)(~.*)?

Then I pass the URL to my site with a suffix of

{R:1}{R:2}

And it now works.
