My first question on here on SF so please forgive me if I manage to bork the post. 🙂
Anyways, I'm using mod_rewrite on one of my machines with a simple rule that redirects to a webapp on another machine. I'm also setting the header 'Access-Control-Allow-Origin' on both machines. The problem is that when I hit the rewrite rule, I loose the 'Access-Control-Allow-Origin' header setting.
Here's an example of the Apache config for the first machine:
NameVirtualHost 10.0.0.2:80
<VirtualHost 10.0.0.2:80>
DocumentRoot /var/www/host.example.com
ServerName host.example.com
JkMount /webapp/* jkworker
Header set Access-Control-Allow-Origin "*"
RewriteEngine on
RewriteRule ^/otherhost http://otherhost.example.com/webapp [R,L]
</VirtualHost>
And here's an example of the Apache config for the second:
NameVirtualHost 10.0.1.2:80
<VirtualHost 10.0.1.2:80>
DocumentRoot /var/www/otherhost.example.com
ServerName otherhost.example.com
JkMount /webapp/* jkworker
Header set Access-Control-Allow-Origin "*"
</VirtualHost>
When I hit host.example.com we see that the header is set:
$ curl -i http://host.example.com/
HTTP/1.1 302 Moved Temporarily
Server: Apache/2.2.11 (FreeBSD) mod_ssl/2.2.11 OpenSSL/0.9.7e-p1 DAV/2 mod_jk/1.2.26
Content-Length: 0
Access-Control-Allow-Origin: *
Content-Type: text/html;charset=ISO-8859-1
And when I hit otherhost.example.com we see that it too is setting the header:
$ curl -i http://otherhost.example.com
HTTP/1.1 200 OK
Server: Apache/2.0.46 (Red Hat)
Location: http://otherhost.example.com/index.htm
Content-Length: 0
Access-Control-Allow-Origin: *
Content-Type: text/html;charset=UTF-8
But when I try to hit the rewrite rule at host.example.com/otherhost we get no love:
$ curl -i http://host.example.com/otherhost/
HTTP/1.1 302 Found
Server: Apache/2.2.11 (FreeBSD) mod_ssl/2.2.11 OpenSSL/0.9.7e-p1 DAV/2 mod_jk/1.2.26
Location: http://otherhost.example.com/
Content-Length: 0
Content-Type: text/html; charset=iso-8859-1
Can anybody point out what I'm doing wrong here? Could mod_jk be part of the problem?
