DESCRIPTION

       I needed a simple and fast routine which can detect whether HTTP client is a GUI browser (like Chrome or
       Firefox), a text browser (like Lynx or Links), or neither (like curl, or L). Hence, this module.

FUNCTIONS

       None are exported by default, but they are exportable.

   detect_http_ua_simple(@args) -> [status, msg, result, meta]
       This function is a simple and fast routine to detect whether HTTP client is a GUI browser (like Chrome or
       Firefox), a text-based browser (like Lynx or Links), or neither (like curl or LWP). Extra information can
       be provided in the future.

       Currently these heuristic rules are used:

       •   check popular browser markers in User-Agent header (e.g. 'Chrome', 'Opera');

       •   check Accept header for 'image/';

       It  is several times faster than the other equivalent Perl modules, this is because it does significantly
       less.

       Arguments ('*' denotes required arguments):

       •   env => any

           CGI-compatible environment, e.g. \%ENV or PSGI's $env.

       Return value:

       Returns an enveloped result (an array). First element (status) is an integer containing HTTP status  code
       (200  means  OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error
       message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth  element
       (meta) is called result metadata and is optional, a hash that contains extra information.
