Deleting a string
NOTE
For more information about offsets, refer to “Explanation of offsets” on page 265.
To configure a request to delete a sub-string in a CSW rule, follow these steps.
1. Define a CSW rule.
Virtual ADX(config)#csw-rule r13 url exists
Syntax: csw-rule rule-name url exists
2. Define a CSW policy.
Virtual ADX(config)#csw-policy mypolicy
Syntax: csw-policy policy-name
3. Specify a primary action.
Virtual ADX(config-csw-mypolicy)#match r13 forward 1025
Syntax: match rule-name forward server-id
4. Specify a dependent rewrite action.
Virtual ADX(config-csw-mypolicy)#match r13 rewrite request-delete string "123"
Syntax: match rule-name rewrite request-delete string string-content
NOTE
The following information assumes you have already completed the previous configuration.
The url-exist matches any URL. If found, only string "123" is deleted; if no instance of "123" is found
in the URL, the original URL is sent to the server.
Example Original HTTP request:
GET /abc/xyz123/index.html HTTP/1.1\r\n
Host: www.example5.com\r\n
User-Agent: Netscape/7.02\r\n
Accept-Charset: ISO-8859-1\r\n
Cookie: name=brocadenet; userid=12345\r\n
