[delon]

I dont know where to exactly put this topic :
i have a friend whever he visits hotmail.com or delon.in ( my website ), He gets an error saying BAD REQUEST and the rest i dont know.

why is this so happening, is there any solution.

Everything happens for a reason.Check into it some more.

If its just your friend then there must be a problem with his computer.

usually it says it because the internet browser is picking something up bad - try installing FireFox or Safari, see if that helps.

he is using firefox

Run a virus/spyware scan and make sure the firewall's not blocking anything (common sense). See if it happens on websites besides yours and HotMail, then try running ipconfig /all from the Command Prompt. Programs > Accessories > Command Prompt or run cmd.exe. What version of Firefox, and what addons/extensions/plugins does he have?
