The second argument of
RewriteRule
isn’t written using the regular expressions language. Indeed,
it doesn’t need to, because it’s not meant to match anything. Instead, it simply supplies the form of the
rewritten URL. The only part with a special significance here is the
$1
variable, whose value is extracted
from the expression between parentheses of the first argument of
RewriteRule
.
As you can see, this rule does indeed rewrite any request for a URL that ends with
Products/P
n
.html
to
product.php?productID=
n
, which can be executed by the
product.php
script you wrote earlier.
At the end of a rewrite rule you can also add special flags for the new URL by appending one or more
flag arguments. These arguments are specific the
RewriteRule
command, and not to regular expres-
sions in general. Table 3-4 lists the possible
RewriteRule
arguments. These rewrite flags must always
be placed in square brackets at the end of an individual rule.
