Cisco Cisco Content Switching Module Guía Para Resolver Problemas

Consider this example, which defines a policy map. The example references both a user−defined url−map and
a serverfarm:

Note: The serverfarm has the name SFARM1 in this example.

map LOWERCASE_ONLY url

  match protocol http url /test*

policy LOWERCASE_ONLY

  url−map LOWERCASE_ONLY 

  serverfarm SFARM1

If you enter http://www.domain.com/Test.html, an error is returned. The error states that the document cannot
be found. The error occurs because you entered an uppercase T, rather than a lowercase t. The CSM sends a
reset (RST) immediately after the CSM receives the client GET request, which results in the error.

For case insensitivity, configure the CSM to allow any possible combination of uppercase and lowercase
characters. Here is an example:

Test

TeSt

TEST

Now, consider this policy map, which references another user−defined url−map with the name ANY_CASE.
This policy map uses regular expressions to allow for case insensitivity:

map ANY_CASE url

  match protocol http url /[T|t][E|e][S|s][T|t]*

policy ANY_CASE

  url−map ANY_CASE

  serverfarm SFARM1

The latter of these two configurations defines the regular expression. The regular expression allows for any
combination of uppercase and lowercase characters for the word "test", which can be followed by any other
sequence of characters. The addition of the wildcard (

*

) denotes any other sequence of characters to follow.
