—One of 

http

, https, ftp, mms, rtsp, tcp, aol-im, msn-im, or yahoo-im

.

The request URL has the scheme 

https

 only in the case of SSL termination. A request URL with 

the scheme 

tcp

 only has a host and a port, and occurs in two cases: when a connection is made to 

a TCP tunnel service port, and when the CONNECT method is used in an explicitly proxied 
HTTP request. For example, when the Web browser has an explicit HTTP proxy and the user 
requests an HTTPS URL, the browser creates a TCP tunnel using the CONNECT method.

•

—A domain name or IP address. Host names must be complete; for example, 

url=http://www

 fails to match a URL such as 

http://www.example.com

. 

This use of a complete 

host instead of a 

 (such as 

example.com

) indicates the difference between the 

url=

 

and 

url.domain=

 conditions.

•

—A pattern which matches either a complete domain name or is a suffix of the 

domain name, respecting component boundaries. An IP address is not allowed. This use of a 

 pattern instead of a complete host name marks the difference between the 

url.domain=

 and 

url=

 conditions.

•

—A port number, between 1 and 65535

.

•

—The 

 portion of a URL is the string beginning with ‘

/

’ that follows the 

host and port, and precedes any URL fragment. A 

 pattern is a string beginning with 

a ‘

/

’ that matches the beginning of the

•

—A string representing a filename extension to be tested, optionally 

preceded by a period (

.

). A quoted empty string (

url.extension=””

) matches URLs that do not
