can configure the ASA to use proxy bypass when applications and Web resources
work better with the special content rewriting this feature provides. Proxy
bypass is an alternative method of content rewriting that makes minimal changes
to the original content. It is often useful with custom Web applications.
You can configure multiple proxy bypass entries. The order in
which you configure them is unimportant. The interface and path mask or
interface and port uniquely identify a proxy bypass rule.
If you configure proxy bypass using ports rather than path
masks, depending on your network configuration, you may need to change your
firewall configuration to allow these ports access to the ASA. Use path masks
to avoid this restriction. Be aware, however, that path masks can change, so
you may need to use multiple pathmask statements to exhaust the possibilities.
A path is everything in a URL after the .com or .org or other
types of domain name. For example, in the URL www.example.com/hrbenefits,
hrbenefits is the path. Similarly, for the URL
hrinsurance is the path. To use proxy bypass for all hr
sites, you can avoid using the command multiple times by using the * wildcard
as follows: /hr*.
You can set rules for when the ASA performs little or no content
