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
       LWP). Hence, this module.

FUNCTIONS

   detect_http_ua_simple($env) -> [status, msg, result, meta]
       Detect whether HTTP client is a GUI/TUI browser.

       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.

       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.

       Return value:  (hash)

       ·   'is_gui_browser' key will be set to true if HTTP client is a GUI browser.

       ·   'is_text_browser' key will be set to true if HTTP client is a text/TUI browser.

       ·   'is_browser' key will be set to true if either 'is_gui_browser' or 'is_text_browser'
           is set to true.
