org.apache.portals.applications.webcontent2.proxy.rewriter.DefaultReverseProxyTextLineContentRewriter

All Implemented Interfaces:

ContentRewriter

public class DefaultReverseProxyTextLineContentRewriter
extends AbstractTextLineContentRewriter

Default text line based content rewriter implementation with basic link rewriting features.

This implementation uses a regular expression (see LINK_PATTERN) to find all the DOM elements containing any of href, src and action attributes and rewrite those URI attribute values by a resolved ProxyMapping from the internal ProxyMappingRegistry in the current reverse proxy processing context.

                      throws ContentRewritingException,
                             IOException

This implementation uses a regular expression (see LINK_PATTERN) to find all the DOM elements containing any of href, src and action attributes and rewrite those URI attribute values (see rewriteURI(String, ContentRewritingContext)) by a resolved ProxyMapping from the internal ProxyMappingRegistry in the current reverse proxy processing context.

Specified by:
