Step3: Install LogWrite.cgi to your Web Server

Before we start to install LogWrite to your Web server, we walk thru the mechanism of LogWriter.
Please see the chart in below.
When visitor comes to index.html in your Web server, LogWriter is automatically invoked from the tags embeded in index.html file. LogWriter will run as CGI program on your server and write a log record to index.wit file.
LogWriter will write factors in below every time it's invoked.

  • Access date and time
  • Visitor's host name
  • Visitor's IP address
  • ReferURL ( Wher are visitors from?)
  • The information of visitor's browser and operationg system.

Then Witness will analyze log records in index.wit file. We call index.wit "Witness Log File".

IMPORTANT: Witness Log File name and location can be changed as needed, but prefix of the file has to be .wit. If you put different prefix to the Witness Log File, it will not be recognized as Witness Log File.

Once you install witness to your computer, you have LogWiter.cgi, LogWriter.pl and LogWriter.csh(for SSI) in server diectory. Please select the one will be fit to your server's environment. The chart in above described LogWriter.cgi.
The box in below explain the installation step by step with the environment you have.
