By default, the rewriter is enabled for all proxy services. The rewriter can slow performance because of the parsing overhead. In some cases, a website might not have content with URL references that need to be rewritten. The rewriter can be disabled on the proxy service that protects that website.
On the Home page, click Access Gateways > Edit > [Name of Reverse Proxy] > [Name of Proxy Service] > HTML Rewriting.
Deselect Enable HTML Rewriting and click OK.
To apply your changes, click the Access Gateways link, and click Update > OK.
Select Access Gateway and click Actions > Purge All Cache > OK.
