By default, the ACE CLI is case sensitive. To disable case-sensitivity matching
for HTTP only, use the case-insensitive command in HTTP parameter map
configuration mode. With case-insensitive matching enabled, the CLI does not
distinguish between uppercase and lowercase letters. When case sensitivity is
disabled, it applies to the following:
HTTP header names and values
•
URL strings
•
HTTP content inspection
•
The syntax of this command is as follows:
case-insensitive
For example, to disable case sensitivity, enter:
host1/Admin(config-parammap-http)# case-insensitive
To reenable case-sensitive matching after it has been disabled, enter:
host1/Admin(config-parammap-http)# no case-insensitive
You can set the maximum number of bytes to parse in HTTP headers by using the
set header-maxparse-length command in HTTP parameter-map configuration
mode. The syntax of this command is as follows:
set header-maxparse-length bytes
The bytes argument is the maximum number of bytes to parse for HTTP headers.
Enter an integer from 1 to 65535. The default is 2048 bytes.
For example, to set the HTTP header maximum parse length to 8192, enter:
host1/Admin(config-parammap-http)# set header-maxparse-length 8192
To reset the HTTP header maximum parse length to the default of 2048 bytes,
enter:
host1/Admin(config-parammap-http)# no set-header maxparse-length
