So this person has been on my forum home page since last few hours. When he visited the forum, he used : hxtp://www.mydomainname.com/?Pragma=no-cache And hours have passed since then and that person is still on my forum home. Could you please suggest me if there is any security risk from this person? I normally don't find people using such strings to disable browser cache. Please guide me! Thanks! Edit: MaxMind Geo location API shows his/her IP location as : Sunnyvale, CA, UNITED STATES
Are you processing this query string? I don't think you need to worry about this. Was it a POST or GET request?
Thanks for the reply, buddy! I found out the problem. Actually, it's a 24 x 7 website monitoring bot that is set to monitor my websites/5 minutes. When this IP stayed on my forum home for longer than 12hrs, I became worried about this thing. Then I checked my other sites and found the same IP with the same string. I think it's the same monitoring bot and that's why it's showing up all the time.
