## 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.
