Description: match strings with backends, regexen and other strings
 Varnish Module (VMOD) for matching strings against sets of fixed
 strings. A VMOD object may also function as an associative array,
 mapping the matched string to one or more of a backend, another
 string, an integer, or a regular expression. The string may also map
 to a subroutine that can be invoked.
 .
 The VMOD is intended to support a variety of use cases that are
 typical for VCL deployments, such as:
 .
  * Determining the backend based on the Host header or the prefix of
    the URL.
  * Rewriting the URL or a header.
  * Generating redirect responses, based on a header or the URL.
  * Permitting or rejecting request methods.
  * Matching the Basic Authentication credentials in an Authorization
    request header.
  * Matching media types in the Content-Type header of a backend
    response to determine if the content is compressible.
  * Accessing data by string match, as in an associative array, or by
    numeric index, as in a standard array.
  * Dispatching subroutine calls based on string matches.
  * Executing conditional logic that depends on features of the request
    or response that can be determined by matching headers or URLs.
 .
 Operations such as these are commonly implemented in native VCL with
 an if-elsif-elsif sequence of string comparisons or regex matches.
 As the number of matches increases, such a sequence becomes cumbersome
 and scales poorly -- the time needed to execute the sequence increases
 with the number of matches to be performed.
 With the VMOD, the strings to be matched are declared in a tabular
 form in vcl_init, and the operation is executed in a few lines.
