The apache server should catch this request and send/rewrite to https://apps.domain.tld/rds/something/something/login.whatever. We have a ssl virtual host and in this virtual host i have a rewrite statement:

RewriteEngine On
RewriteLog /var/log/apache2/rewrite.log
RewriteLogLevel 3
RewriteCond %{HTTP_HOST} ^apps\.
RewriteCond %{HTTPS} on
RewriteRule ^/(.*) https://192.168.123.7/sub/ [R]
OK, i have turned on rewrite log and this is what i get in the log:
initial] (2) init rewrite engine with requested uri /
/initial] (3) applying pattern '^/(.*)' to uri '/'
/initial] (3) applying pattern '^/(.*)' to uri '/'
/initial] (2) rewrite '/' -> 'https://192.168.123.7/rdweb/'
/initial] (2) explicitly forcing redirect with https://192.168.123.7/rdweb/
/initial] (3) applying pattern '^/(.*)' to uri 'https://192.168.123.7/rdweb/'
/initial] (1) escaping https://192.168.123.7/rdweb/ for redirect
/initial] (1) redirect to https://192.168.123.7/rdweb/ [REDIRECT/302]
As you can see this works fine. However, i am on the same network segment as 192.168.123.7 and the URL in the browser is
https://192.168.123.7/sub/sub/sub/login.whatever and this does not/will not work when not on the same network segment. So i changed the rewriterule to:
RewriteEngine On RewriteLog /var/log/apache2/rewrite.log
RewriteLogLevel 3
RewriteCond %{HTTP_HOST} ^apps\.
RewriteCond %{HTTPS} on
RewriteRule ^/(.*) https://apps.domain.tld/sub/ [R]
and this is in the rewrite log from the above:
/initial] (2) init rewrite engine with requested uri /sub/
/initial] (3) applying pattern '^/(.*)' to uri '/syb/'
/initial] (3) applying pattern '^/(.*)' to uri '/sub/'
/initial] (2) rewrite '/sub/' -> 'https://apps.domain.tld/sub/'
/initial] (2) explicitly forcing redirect with https://apps.domain.tld/sub/
/initial] (3) applying pattern '^/(.*)' to uri 'https://apps.domain.tld/sub/'
/initial] (1) escaping https://apps.domain.tld/sub/ for redirect
/initial] (1) redirect to https://apps.domain.tld/sub/ [REDIRECT/302]
/initial] (2) init rewrite engine with requested uri /sub/
/initial] (3) applying pattern '^/(.*)' to uri '/sub/'
/initial] (3) applying pattern '^/(.*)' to uri '/sub/'
/initial] (2) rewrite '/sub/' -> 'https://apps.domain.tld/sub/'
/initial] (2) explicitly forcing redirect with https://apps.domain.tld/sub/
/initial] (3) applying pattern '^/(.*)' to uri 'https://apps.domain.tld/sub/'
/initial] (1) escaping https://apps.domain.tld/sub/ for redirect
/initial] (1) redirect to https://apps.domain.tld/sub/ [REDIRECT/302]
And this keeps repeating until i stop it. This looks like the rewrite loop but i am under the impression that by default max redirects=10 and should stop after 10.
Any ideas as to what is going on with the rewrite statements?
