Configuring Apache HTTP for changing context URL
First of all you must have one of these configurations running on your server:
On the sample below the http://openkm.your-domain.com/OpenKM/frontend has been rewrited to http://openkm.yourdomain.com/frontend
Enable the headers module:
$ sudo a2enmod headers
To change /OpenKM application context try this as your VirtualHost configuration:
<VirtualHost *:80>
ServerName openkm.your-domain.com
ProxyPass /frontend/webSocket ws://localhost:8080/OpenKM/frontend/webSocket
ProxyPassReverse /frontend/webSocket ws://localhost:8080/OpenKM/frontend/webSocket
ProxyPass / ajp://localhost:8009/OpenKM/
ProxyPassReverse / http://openkm.your-domain.com/OpenKM/
RequestHeader edit X-GWT-Module-Base ^(http://openkm.your-domain.com)/frontend/(.*)$ $1/OpenKM/frontend/$2
ProxyPassReverseCookiePath /OpenKM /
ErrorLog /var/log/apache2/openkm-error.log
CustomLog /var/log/apache2/openkm-access.log combined
</VirtualHost>You need also set the configuration parameter system.apache.request.header.fix to on (true).
