Functions
Variable
Description
$(number)
Expands
to

the

corresponding

matching

subexpression
(by
number)
in
the

URL

pattern.

Subexpressions

are

marked

in

a

URL

pattern
using
parentheses

().

The

numbering

of

the

subexpressions

begins
with
1

and

is

the

number

of

the

left-parenthesis

“(“

counting

from
the
l

eft.

You

can

specify

any

$(0)
matches
the

entire

URL.

For

example,

if

the

URL

pattern

is
((http://server/.*)/(.*)/)a.jsp,
and

the

URL

that

matches

it

is
http://server/main/sub/a.jsp?category=shoes&session=99999,
then
the
following

are

correct:
$(0)
=

http://server/main/sub/a.jsp
$(1)
=

http://server/main/sub/
$(2)
=

http://server/main
$(3)
=

sub
If
the

specified

subexpression

does

not

exist

in

the

URL

pattern,
then
the

variable

expands

to

the

empty

string.
$http_query_string()
Expands
to

the

value

of

the

whole

query

string

in

the

URL.

For
example,
if

the

URL

is
http://myhost/dothis?param1=value1&param2=value2,
then

the
following
is

correct:
$http_query_string()
=

pa

ram1=value1&param2=value2
This
function

applies

to

both

GET

and

POST

requests.
