retrict page access count

[Ian]

hi

is there a simple way to restrict the number of times a given user (IP) can
access a given page in a day?

i want to guard against the bulk extraction of data from my site through
"scripts".

thanks
ian

If you restrict pages based upon the user's IP address, you'll end up with
legitimate users that can't access your web site. This issue is addressed
in my previous post. There are a lot of users that are behind NAT servers
and web caching servers that mask the user's true IP address. In this case,
you can litterally have thousands of users reporting the same IP address.

You are better off creating a challenge/response shcema to prevent scripts
from downloading your site. The most popular one that I have seen is a
server generated image that displays a series of letters and numbers (like a
password) that the user must type in to gain access to your site. I'm sure
that a similar text based schema can be created to serve the same purpose,
but I haven't seen one in use.
