d. Enable or disable cache redirection of requests that contain the string "Cache-control:no
cache" in the HTTP 1.1 header or the string "Pragma:no cache" in the HTTP 1.0 header to
the origin server.
• ena—Alteon redirects all requests that contain the string “Cache-control: no cache” in
the HTTP 1.1 header or the string “Pragma:no cache” in the HTTP 1.0 header to the
origin server.
• dis—Alteon compares the URL against the expression table to determine whether the
request should be redirected to a cache server or the origin server.
4. Define the strings to be used for cache SLB:
— addstr—Add a string or a path.
— remstr—Remove string or a path.
A default string any indicates that the particular server can handle all URL or cache requests.
Refer to the following examples:
Example 1: String Starting with the Forward Slash (/)
A string that starts with a forward slash (/), such as "/images," indicates that the server will process
requests that start with the "/images" string only.
With the "/images" string, the server will handle these requests:
/images/product/b.gif
/images/company/a.gif
/images/testing/c.jpg
The server will not handle these requests:
/company/images/b.gif
/product/images/c.gif
/testing/images/a.gif
Example 2: String Without the Forward Slash (/)
A string that does not start out with a forward slash (/) indicates that the server will process any
requests that contain the defined string.
With the "images" string, the server will process these requests:
/images/product/b.gif
/images/company/a.gif
/images/testing/c.jpg
/company/images/b.gif
/product/images/c.gif
/testing/images/a.gif
Example 3: String with the Forward Slash (/) Only
If a server is configured with the load balance string (/) only, it will only handle requests to the root
directory.
