host name is www.myhost.com or www.myhost.

All text operations that you specify after this prefix are 
case insensitive.

HTTP.REQ.METHOD

Returns the value of the METHOD in an HTTP request, 
or matches the method type if you provide it as an 
argument, for example, http.req.method.
eq(get)

. If you enclose the argument in quotes, 

evaluation is case-sensitive.

HTTP.REQ.URL 

Returns the HTTP URL.

HTTP.REQ.URL.HOSTNAME

Returns the host name in the HTTP URL. 

Do not use this prefix in bidirectional policies.

Note that there are two similar prefixes that return host 
names, as follows:

• HTTP.REQ.HOSTNAME returns the host name 

from the URL if there is one; otherwise, it returns 
the value in the last occurrence of the Host header.

• HTTP.REQ.HEADER(

"

Host

"

)

 only returns the 

value from the Host header. To use this value as a 
host name you must typecast this string, as 
illustrated in the following example: http.req.
header(

"

host

"

).typecast_http_

hostname_t

For more information on typecasting, see
