Acceleration
Acceleration provides a technology solution to speed up web application response and optimize web pages and resources in real time.
As a module on FortiWeb device, Acceleration is simple to deploy and does not require any integration into Web application servers or any client installation on end-user devices. With this feature, you can select the approach(es) to make your web site faster and more user-friendly.
An Acceleration policy specifies the option(s) for optimizing the delivery of web applications. To take full advantage of the benefits that Acceleration offers, you must first create your own Acceleration policy, and then select the policy in Policy > Server Policy.
You can also specify certain URLs to be skipped for web application delivery optimization, and add the exception items to the acceleration policy.
FortiWeb offers options for optimizing the delivery of the following web content:
- HTML
- JavaScript
- CSS
Acceleration is available in Reverse Proxy, True Transparent Proxy, and WCCP operating modes.

Depending on your selection in Type, enter either:
-
Simple String—Enter a literal URL, such as
/folder1/index.htmthat the HTTP request must contain in order to match the rule, or use wildcards to match multiple URLs, such as/folder1/*or/folder1/*/index.htm. The URL must begin with a slash (/). -
Regular Expression—A regular expression, such as
^/*.php, matching the URLs to which the rule should apply. The pattern does not require a slash (/).
Do not include the domain name, such as
www.example.com, which is configured separately in Host.To test a regular expression, click the >> (test) icon. This icon opens the Regular Expression Validator window from which you can fine-tune the expression. For details, see Regular expression syntax and Cookbook regular expressions.
