Use "Redirect" and "ProxyPass"

Question

I would like to force my users to use https to log in. Unfortunately the "redirect" directive does not seem to work in cunjunction with "ProxyPass"

<VirtualHost *:80>
  ServerName www.domain.com
  # This does not work
  Redirect permanent /app/login.jsp https://www.domain.com/app/login.jsp
  ProxyPass         /app    http://localhost:8080/app
  ProxyPassReverse  /app    http://localhost:8080/app
</VirtualHost>

Any idea ? Thanks.

Found an answer to this question here:

The following needs to be added before the other proxypass directives:

ProxyPass /app/login.jsp !

Answer 2

I had a more complicated use case and it required the use of ProxyPassMatch. It went a little something like this:

ProxyPassMatch ^/app(/(index.html)?)?$ !
RedirectMatch ^/app(/(index.html)?)?$ /path/to/login/page.html

ProxyPass /app/* http://remote-server/app
ProxyPassReverse /app/* http://remote-server/app

I had to use ProxyPassMatch because ProxyPass otherwise performs prefix-matching. You need to match on the end-of-string, so ProxyPassMatch with a $ regular expression metacharacter is critical.

Here, RedirectMatch is used in the same way, because Redirect also performs prefix-matching as well. The two directives also have a nice symmetry, too.
