Download here hl booster.rar , unzipp it (directly in addons or copy the booster folder in HLDS\cstrike\addons, (HLDS is the directory where you have the server), then edit in HLDS\cstrike\addons\metamod\plugins.ini, the line:win32 addons\hlbooster\dlls\booster_mm.dll. Very important!!!! In order to work, in the HLDS\cstrike\server.cfg you have to write the next line:

This plugin allows you to see and administrate, in some limits, your counter strike 1.6 server, using a web browser like Internet Explorer or Mozzila Firefox.
Download it here and copy the "w" folder in HLDS\cstrike\addons and edit it in metamod\plugins.ini :

win32 addons\w\dlls\w_mm.dll

Save and close, and if the server was started, restart.
To see your server o the browser, acces the http://xx.xxx.xxx.xxx:port page, where xx... is the server's ip, and “port” is its port, which is usually 27015 (if you haven't changed it). There you will be asked to log on and you use the RCON password (the one you write on the console when you start the server). Anyone can access this address, but only the ones who know the RCON password can administrate it.
