Disabling The Rewriter - Novell ACCESS MANAGER 3.1 SP2 - ACCESS GATEWAY GUIDE 2010 Manual

1.5.6 Disabling the Rewriter

There are three methods you can use to disable the internal rewriter:
"Disabling per Proxy Service" on page 67
"Disabling per URL" on page 67
"Disabling with Page Modifications" on page 67
Disabling per Proxy Service
By default, the rewriter is enabled for all proxy services. The rewriter can slow performance because
of the parsing overhead. In some cases, a Web site might not have content with URL references that
need to be rewritten. The rewriter can be disabled on the proxy service that protects that Web site.
1 In the Administration Console, click Devices > Access Gateways > Edit > [Name of Reverse
Proxy] > [Name of Proxy Service] > HTML Rewriting.
2 Deselect the Enable HTML Rewriting option, then click OK.
3 To apply your changes, click the Access Gateways link, then click Update > OK.
4 Select the Access Gateway, then click Actions > Purge All Cache > OK.
Disabling per URL
You can also specify a list of URLs that are to be excluded from being rewritten for the selected

the top of the list, then click OK.
6 To apply your changes, click the Access Gateways link, then click Update > OK.
7 Select the Access Gateway, then click Actions > Purge All Cache > OK.
Disabling with Page Modifications
There are cases when the URLs in only part of a page or in some of the JavaScript or form can be
rewritten and the rest should not be rewritten. When this is the case, you might need to modify the
content on the Web server. Although this deviates from the design behind Access Manager, you
might encounter circumstances where it cannot be avoided.
You can add the following types of tags to the pages on the Web server:
