Syntax: match rule-name rewrite request-replace matched-string new-string
The rule-name variable defines the name of CSW rule.
The matched-string keyword defines the matched string (defined by CSW rule), which is to be
replaced.
The new-string variable defines the new string that replaces the previous string.
NOTE
The following information assumes you have already completed the previous configuration.
The url-exist matches the entire URL, so the matched string is the whole URL
"/abc/xyz/index.html." It is replaced by the new string "/newabc/newxyz/newindex.html."
Example Original HTTP request:
GET /abc/xyz/index.html HTTP/1.1\r\n
Host: www.example5.com\r\n
User-Agent: Mozilla/5.0 Netscape/7.02\r\n
Accept-Charset: ISO-8859-1\r\n
Cookie: name=brocadenet; userid=12345\r\n
\r\n
Example Rewritten HTTP request:
GET /newabc/newxyz/newindex.html HTTP/1.1\r\n
Host: www.example5.com\r\n
User-Agent: Mozilla/5.0 Netscape/7.02\r\n
Accept-Charset: ISO-8859-1\r\n
Cookie: name=brocadenet; userid=12345\r\n

Replace a defined string
To configure a request to replace a specific string in a CSW rule match, follow these steps.
1. Define a CSW rule for HTTP URL content.
Virtual ADX(config)#csw-rule r32 url pattern "abc"
Syntax: csw-rule rule-name url pattern pattern-content
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 r32 forward 1025
Syntax: match rule-name forward server-id
4. Specify a dependent rewrite action
Virtual ADX(config-csw-mypolicy)#match r32 rewrite request-replace string
"xyz" "1234"
Syntax: match rule-name rewrite request-replace string old-string new-string
The rule-name variable defines the name of the CSW rule.
