# mod\_browser(3erl)

Tries to recognize the browser and operating-system of the client.

## NAME

mod\_browser - Tries to recognize the browser and operating-system of the client.

## DESCRIPTION

When a client requests for an asset the request-header may contain a string that identifies the product. Many browsers also sends information about which operating-system the client use. This can be used in conjunction with mod\_esi to tailor the response according to the users operating-system and browser.

This module can be used to recognize the browser and operating-system of the client in two ways either as a module in the EWSAPI response chain or by a separate call to the function *getBrowser/1*.

## EXPORTS

**getBrowser(AgentString)-\> {Browser,OperatingSystem}**\

- Types

  AgentString = string()\
   Browser = {Name, Version}\|unknown\
   OperatingSystem = win3x\|win95\|win98\|winnt\|win2k\|sunos4\|sunos5\| sun\|aix\|linux\|sco\|freebsd\|bsd\|macosx\|unknown\
   Name = opera\|msie\|netscape\|lynx\|mozilla\| emacs\|soffice\|mosaic\|safari\
   Version = float().\

The function *getBrowser/1*, tries to detect which browser and operating system the user has. Note that the answer is just a best guess since some browsers can identify themselves as other browsers, read Opera.

## EWSAPI MODULE INTERACTION

Exports the following EWSAPI interaction data, if possible:

- ***{'user-agent', AgentData}*:**

  Where *AgentData* is the same as the return value from *getBrowser/1*. Note that the answer is just a best guess, since some browsers can identify themselves as other browsers, read Opera.
