Now a day, WWW has become important and huge data storage. All users' activities will be stored in log file. The log file shows the interest on the particular website. With a wide usage of internet, the log file size is growing rapidly. Web mining is the process of extracting information from web data. The raw log file won't reveal the users' accessing pattern. Thus, preprocessing has become an important process in web mining. Web Usage Mining is the important domain area of web mining to extract and analyze the usage pattern of users from the server log file. The quality of the input decides the quality of the output. Preprocessing is the noteworthy process before mining the interesting information from data. In this paper we have implemented the preprocessing techniques to convert the log file into user sessions which are suitable for mining and reduce the size of session file by filtering the least requested pages.
