When I click in my e-mails on a link to a website, I often get a remark:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.


I asked my provider KPN if they can solve this issue, but they informed me that this problem is related to the browser I use, in this case Firefox. Therefor they can't support me with this. I already updated Firefox to version 4.0 but they problem resists.

Can someone please help me out, while I had this problem not in the past.

Thanks in advance.

Hello Cor-el

Thank you for the quick reply. I did the 2 options you mentioned and as far as I can see now, the problem has been solved, great ! I will see if I have to clean it everyday or once or twice a week.

Thanks again.
