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.
