NAME¶

SHARYANTO::HTTP::DetectUA::Simple - A very simple and generic browser detection library

VERSION¶

version 0.67

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¶

detect_http_ua_simple(@args) -> [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

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:

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.
