Request Forwarding
Pluggable Transport Protocol proxying: Requests to Sling are always HTTP based; proxied requests may be HTTP, FTP, or others.
Pluggable Request and Response translation: Input requests can be translated to SOAP requests with responses translated back according to expected formats such as JSON, XML, HTML, etc.
Request URL mapping to proxied request URL (e.g. using URL templates)
Configuration defined in the repository for ResourceProvider services:
- Resource Type indicating Proxy root; e.g. sling:resourceType = proxy
- Proxy URL; e.g. proxyUrl=http://the.target.com
- etc
ProxyResourceProvider controller registers ResourceProvider services based on the proxy configurations with the respective root addresses.
Example: ResourceProvider registered at /proxy
- proxyUtl=http://the.target.com
- Map /proxy.html ==> http://the.target.com/
- Map /proxy/foo.html ==> http://the.target.com/foo
