google analytics ကိုေလ့လာၾကည့္ရင္းက web logs ေတြလုပ္ရင္းမရလုိက္တဲ့ ဟာေတြကို တကယ္ကို လုိခ်င္မိျပန္တယ္။

User Identifcation in Preprocessing WUM (cs-username)

In cs-username field , it only show “-” eventhough i used “forms authentication” in ASP.NET and IIS 5.1, Visual Studio 2005,Windows XP. I’m confused about it. In web usage mining’s user identification phase, we can idenfiy users by authenticated user or heuristics (IP,Agent,Refer) .
In my thesis,i ‘ll use authenticate user id . I use Forms authentication ,no-anonymous login . So,when user login , IIS web server logs the login user name in cs-username . But it doesn’t happen what i expected . cs-username field is “-” . Why?

IIS userautentication logs “DOMAIN\USER” as windows log in so, forms authentication, do i need to use ISAPI (Internet Server Application Programming Interface)
to get the login user name in cs-username ? Is it possible?

At first, i think
1. by using Login user, it is more easy to identify user.
2. i mine the web server logs of my own web site so “user login” identification is more suitable than IP,Agent,Referer Heuristics.

Disadvantages:
1. I’m in the stack . i can’t identify user because login user name doesnt’ appear in cs-username field (IIS Logs)
2. I’m not sure right now that i could do it with that cs-username. (in theoritically ,WUM useridentifcation can be made by authenticate user but, IIS & ASP.NET i ‘m not sure)
3. if i do it & if only it’s ok , i’m not sure my supervisors like that kind of user identification.
(Teachers may ask ” is it necessary to login ? why do i browse the books without registration”)
Another Approach:
I can use IP,Agent,Refer instead of Login for user identification .
There’r also problems .
1. I user one PC to login so IP address will be “localhost(127.0.0.1) . I can use agents as Firefox,Opera,IE.
2. Normally, users are visited web sites from many IP addresses so it is ok to use IP address .Some users use 1 proxy address so IP address will be the same .

Q::::can i make login username in cs-username field in IIS logs ????

Preprocessing in WUM (Program)

First program is “Loading the web server logs using user specified date range” . & then i have to preprocessing these logs to form the sequence database. Preprocessing include 1. data cleaning ( to remove .jpg extension ; to remove the page except status code is 200 (successful) )

2.User Identification ( i want to use with cs-username in IIS log but there’s a problem. *** I use Forms Authentication with no anonymous login but cs-username field is still “-” in logs. I have to solve this problem when I write a BookStore Web Site*** ) or (I have to use IP & user Agent to identify user,but there ‘s also a problem ‘cos I use 1 PC (WindowsXP , IIS5.1 , VS2005 ) to test my website so my ip address is “localhost” ; most of the other web usage mining thesis use logs from many sites so they don’t use cs-username; In my case , I built my web site & i use “Login username ” ,i think cs-username field must be filled with login-username” but i ‘v heard that if i use the IIS authentication, cs-username field is filled with DOMAIN\USER like widows logon user )

3. session identification ( after user identification – using cs-username or heuristics IP & UserAgnet) , i have to sessioniaze with timeout (30 minutes default)  . another way is Referer .

After sessionization , i ‘ll get the sequence Database (sid,sequence) ; I have to show this output to the teacher ; this is the first part .
