Question
Password protection and redirection using ASP
I wish to create a login page which will take in the user/pass combo, check them against a database and then redirect them to a start page that is stored in the database. I want all the pages that each loged in user sees to be protected and to only be accessible with the correct user/pass. I also need to create a form that will sign up new users and enter their data into a database. I am a newbie to ASP so as much step through on step as could be provided would be appreciated. I'm also in a time crunch on this. I've tried to use some of the previous answers to a similar question, but I haven't quite gotten what I'm looking for. Thanks.

The code above assumes that your login page is 'logon.htm' and that upon successful validation, you want your user to go to main.asp.
Also, you will need to update this line to match your environment:
strDataPath = Server.MapPath("family.mdb
Finally, you will need to put this at the top of each page that you want protected (or better yet, put it in an include file):
if (not Session("bolAuthenticated"
response.redirect("logout.
end if
if Session("iID") < 1 then
response.redirect("logout.
end if
Sorry, a few more changes (i am trying to do this quickly as you said that it is urgent).
Add one more field to your tblUsers: intID which should be an autocounter field.

I'm still not getting this to work. I just want to get a logon process that takes the password and user and comparies them to the database, and then redirects the user to a start page that is stored in the database. Again making sure that all these pages are protected is key. Any help would be appreciated I've been extended a little more time.
Okay, but do we know for sure that you have a table called tblUsers? Also, you will have to change the connection string from:
strDataPath = SErver.MapPath("family.mdb
to:
strDataPath = SErver.MapPath("homebuilde
This assumes that the database is in the same directory that your page is (something that we can change later).

Step 1) Create a form with two fields: strUserName, strPassword
Once this is done, let me know.
