Package sunlabs.brazil.filter
Class UrlMapFilter
java.lang.Object
sunlabs.brazil.filter.UrlMapFilter
Filter to Map url's from any proxied content.
The
MultiProxyHandler
is used to virtually mount other web sites
into the local document root. In the process, it rewrites all the
local url's found in the proxied content to point to the locally mounted
version.
This filter examimes content derived from non-proxied sources for absolute url's to proxied sites, and rewrites them to point to the virtual mount point on the local machine instead of directly to the mounted site.
