Chapter 4 Advanced Expressions: Evaluating Text 69

HTTP Expression Prefixes that Return Text

Prefix	Description
HTTP.REQ.URL.HOSTNAME.	Returns the domain name part of the host name. For
DOMAIN	example, if the host name is www.myhost.com or www.
	myhost.com:8080, the domain is myhost.com.
	This operation returns incorrect results if the host name
	has an IP address. For information on expressions for IP
	addresses, see “Advanced Expressions: IP and MAC
	Addresses, Throughput, VLAN IDs,” on page 149.
	All text operations that you specify after this prefix are
	case insensitive unless explicitly set by the SET_
	TEXT_MODE operator.
HTTP.REQ.URL.HOSTNAME.	Returns the server name part of the host name. For
SERVER	example, if the host name is www.myhost.com or www.
	myhost.com:8080, the server is www.myhost.com.
	All text operations that you specify after this prefix are
	case insensitive.
HTTP.REQ.URL.PATH	Returns a slash- (/) separated list from the path in a
	URL.
	For example, if the URL is http://www.myhost.com/a/b/
	c/mypage.html?a=1, this prefix returns the string /a/b/c/
	mypage.html.
	The expression http.req.url.path.get(1)
	returns "a" from the preceding URL. For more
	information on the GET operation, see “Expressions
	for Extracting Segments of URLs,” on page 129.
HTTP.REQ.URL.PATH_AND_	Returns the portion of the URL that follows the host
QUERY	name.
	For example, if the URL is http://www.myhost.com/a/b/
	c/mypage.html?a=1, this prefix returns /a/b/c/mypage.
	html?a=1.
HTTP.REQ.URL.PROTOCOL	Returns the protocol in the URL.
	This prefix cannot be used in bidirectional policies.
	Following is an example:
	http.req.hostname + http.req.url.
	protocol
HTTP.REQ.URL.QUERY	Returns a name-value list, using the delimiters “=” and
	“&”, from the query component in the URL.
	Following is an example:
	http.req.url.query.contains("viewReport
	&& my_pagelabel")
