Configuring Rules and Actions for Policy Maps

• N/A—Indicates that this attribute is not set.

• False—Indicates that this rule is not to precede another rule in the policy map.

Table 12-32 Layer 7 HTTP Optimization Match Condition Types

Match Condition Type Procedure

Cookie Indicates that an HTTP cookie is to be used to establish a match condition.

1. In the Cookie Name field, enter a unique cookie name. Valid entries are unquoted text strings

with no spaces and a maximum of 64 alphanumeric characters.

2. In the Cookie Value field, enter a unique cookie value expression. Valid entries are unquoted

text strings with no spaces and a maximum of 255 alphanumeric characters.

3. In the Secondary Cookie check box, do one of the following:

–

Clear the check box to indicate that the cookie being defined is a primary cookie.

–

Check the check box to indicate that the cookie being defined is a secondary cookie. You

can specify the delimiters for cookies in a URL string by using an HTTP parameter map

(see the “Configuring HTTP Parameter Maps” section on page 8-2).

Header Indicates that an HTTP header is to be used to establish a match condition.

1. In the Header field, select one of the predefined HTTP headers to be matched, or select HTTP

Header to specify a different HTTP header.

2. If you select HTTP Header, in the Header Name field, enter the name of the HTTP header to

match. Valid entries are unquoted text strings with no spaces and a maximum of 64

alphanumeric characters.

3. In the Header Value (Bytes) field, enter the header value expression string to compare against

the value in the specified field in the HTTP header. Valid entries are text strings with a

maximum of 255 alphanumeric characters. The ACE appliance supports regular expressions

for matching. To include spaces in the string, enclose the entire string in quotes. All headers

in the header map must be matched. See Table 12-33 for a list of the supported characters that

you can use in regular expressions.

HTTP URL Indicates that a portion of an HTTP URL is to be used to establish a match condition.

1. In the URL Expression field, enter a URL or a portion of a URL to match. Valid entries are

URL strings from 1 to 255 alphanumeric characters and include only the portion of the URL

following www.hostname.domain. For example, in the URL

www.anydomain.com/latest/whatsnew.html, include only /latest/whatsnew.html.

2. In the Method Expression field, enter the HTTP method to match. Valid entries are method

names entered as unquoted text strings with no spaces and a maximum of 64 alphanumeric

characters. You can enter either one of the standard HTTP 1.1 method names (OPTIONS,

GET, HEAD, POST, PUT, DELETE, TRACE, or CONNECT) or a text string that must be

matched exactly (for example, CORVETTE).
