URL Rewriting Filter
This URL rewriting option allows you to do a simple string substitution of a base URL and define a point in the URL from which to start the new query string. You can define a single exception to the rewrite and select whether the proxyprefix should be applied or not.
Source URL: Domain name + any other continuous component of URL that defines the URLs to be changed (e.g. http://mywebsite/something/).
Safe URL string: Don't change the base URL if it contains this string (e.g. entering 'view' here will cause http://mywebsite/something/view to not be matched). This can be blank.
Destination URL: Replace the Source URL with this
Query key: Sub-string in original URL after which you start the query string in the new URL (e.g. a key of 'vk' means start the new query string immediately after the point where 'vk=' appears in the source URL). This enables you to remove some non-essential characters from the source URL. Leave this blank to keep the query string unchanged.
Add proxy prefix: Is the proxyprefix required for this URL?
