Configuring an Apache Web Server as a Reverse Proxy

Requirements

Apache Web Server 2.2 or higher with the following modules:

• Substitute
• SSL
• Rewrite

Example assumptions

Old Application Path: http://mysite.com/myapp

New Application Path: http://mysite.com/apps/myapp

Proxy Server: mysite.com

OutSystems Server: server.local

Extra Path in URL: /apps/

Configuration for HTTP

This configuration can be added to the main httpd.conf file, or to a separate file under the user-specific configurations folder. The latter is usually the conf.d folder.

< VirtualHost *:80 >

ProxyPreserveHost On
RewriteEngine on

#Global Rules
ProxyPassMatch /apps/(?!LifeTimeSDK|LifeTimeCore|lifetime|PerformanceMonitor)(.*) http://server.local/$1
ProxyPassReverse /apps/ http://server.local/

#Mod rewrite rules
RewriteRule "^/(?!apps)(.*)" "http://mysite.com/apps/$1" [R]
AddOutputFilterByType SUBSTITUTE text/html
AddOutputFilterByType SUBSTITUTE text/javascript

#Fix for Service Center eSpace and Extension publish
Substitute s|http(.*)://(.*)/ServiceCenter/|http$1://$2/apps/ServiceCenter/|i

#Fix AppFeedback / ECT in Javascript
Substitute s|"/ECT_Provider/|"/apps/ECT_Provider/|i
Substitute s|'/ECT_Provider/|'/apps/ECT_Provider/|i

#LifeTime Management Console
ProxyPassMatch /apps/LifeTimeSDK/(.*) http://lifetime.server/LifeTimeSDK/$1
ProxyPassMatch /apps/LifeTimeCore/(.*) http://lifetime.server/LifeTimeCore/$1
ProxyPassMatch /apps/lifetime/(.*) http://lifetime.server/lifetime/$1

ProxyPassMatch /apps/PerformanceMonitor/(.*) http://lifetime.server/PerformanceMonitor/$1

​< / VirtualHost >

Configuration for HTTPS

This configuration is added to the ssl.conf configuration file, which by default is the ssl.conf under the user-specific configurations folder, and between the virtual host tags.
