The output from applications is rewritten in four stages. HTML, XHTML, and WML are supported in the code as distributed.#.
- JTidy: If the cw_tidy attribute is on, the application's output is run through JTidy to convert it from HTML to well-formed XHTML.
...
- AbsoluteURLFilter: This converts relative URLs to absolute ones.
...
- CWebProxyURLFilter: Rewrites URLs according to cw_passThrough or cw_download.
...
- XSLT: The XML is passed through a stylesheet according to the channel parameters and the media type. Static and runtime data parameters are passed to the stylesheet. This feature is not used by the distributed stylesheets, but may prove useful to custom-written stylesheets, particularly those with no URL Filters.
CWebProxy will use the same method (GET or POST) to call the application as was used to call the portal. Since the portal is intercepting HTTP requests aimed at the application, this will result in the correct method being used, according to what the application expects.
