Will block thousands of IP by IIS depress performance Want to know if performance will down if block too much IP Eric
These days tooooo much spider fake as IE or something else and crasy claw pages from thousands of different IPs.
I am serious thinking block them automatically after caught by spider-trap.
So here is problem, if I do it, maybe will block thousands of IP all the time even I move the IP not come for one month.
Does this worth it? Will block too many IPs lower down the performance of IIS.
There are many threads here on blocking IPs [ google.com]. There are certainly different schools of thought out there on the best way to do it. How would you be handling this on IIS?
I make a spider trap page, blocked by robots.txt file, and in a hidden link the normal visitor cannot see. The result is effective, caught lots of spiders, and put the IPs into a txt file. The last step is use asp.net load the IPs into IIS settings automatically.
