Rewrite with ProxyPass in case of SSL

Can Rewrite be used along with Proxypass?

[Gilraen]

Hey,

ProxyPass /abc/ http://www.example.com:8181/abc/
ProxyPassReverse /abc/ http://www.example.com:8181/abc/

<VirtualHost *:443>
SSLProxyEngine On
ProxyPass [example.com:443...] [example.com:8443...]
ProxyPassReverse [example.com:443...] [example.com:8443...]
</VirtualHost>

<VirtualHost *:80>
RewriteEngine on
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ [%{SERVER_NAME}%{REQUEST_URI}...] [L,R]
</VirtualHost>

I'm using the above piece of code to redirect from http to https. Also, I'm using proxypass to redirect from port 443 to port 8443. (My Apache web server is on port 443 while my tomcat[which has my application] is on port 8443). All this works fine if i enter [example.com...] or http://www.example.com/abc/ in my url. The problem is that I also want [example.com...] or http://www.example.com/ to redirect to [example.com...] (I think this is called internal rewrite?). For this, I changed the above code to look like this:

ProxyPass /abc/ http://www.example.com:8181/abc/
ProxyPassReverse /abc/ http://www.example.com:8181/abc/

<VirtualHost *:443>
/**added this**/
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/abc/(.*)$
RewriteRule ^/(.*)$ [example.com...] [R,L]
/**end**/

SSLProxyEngine On
ProxyPass [example.com:443...] [example.com:8443...]
ProxyPassReverse [example.com:443...] [example.com:8443...]
</VirtualHost>

<VirtualHost *:80>
RewriteEngine on
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ [%{SERVER_NAME}%{REQUEST_URI}...] [L,R]
</VirtualHost>

This does not work. If i enter [example.com...] in my browser url, then it goes to default Tomcat home page! The same procedure (Rewrite + proxypass) works fine when I am only dealing with non-ssl (http). Can anyone see what's wrong with above code.

Hey,

I have been working on this all day..
Please do help!

One more issue I just noticed in this:
If i enter "http://www.example.com/abc" without any trailing slash, then it doesn't redirect properly.

Any Ideas?

Your "day" may be 8 to 16 hours different than the contributors' "day" here. Also, there are many "askers" and few contributors, so please be patient. This is not instant messaging.

Two comments:

There is no need to check the %{SERVER_PORT} in a <VirtualHost> container which is already qualified by a port number.

Your missing trailing slash URL doesn't work because your pattern requires that trailing slash. Modify the pattern to make that slash optional, or detect and redirect slashless requests to add the slash -- This latter method also prevents duplicate-content problems (the same content at two or more different URLs).

I intend to help, but simplify first, then add complexity in small increments to avoid a debugging nightmare.

Ok here's how things stand:

I can redirect from http://www.example.com/ to http://www.example.com/abc/ easily with a simple rewrite statement. But the procedure does not work with https.

Why so?

[jdMorgan]

Please give us something to work with here. What does the relevant code look like now?

Jim

[Gilraen]

This part was supposed to rewrite [example.com...] to [example.com...]

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/abc/(.*)$
RewriteRule ^/(.*)$ [example.com...] [R,L]

But it doesn't work.

[jdMorgan]

Do you have Options FollowSymLinks or SymLinksIfOwnerMatch set in this context? One or the other is required to enable mod_rewrite.

Anything in your server error log?

What happens if you simplify that rule to an unconditional redirect to google.com, and test that?

[Gilraen]

i think my rewrite is working fine.. initially i had used the same code to redirect from http://www.example.com/ to http://www.example.com/abc/. That had worked.

Note: I want the same for httpS.
