Hi,
I found a rare 500 error in the error logs today, but I'm not sure why it happened. A real customer, who actually bought something, was looking at a product and all of a sudden they started to get 403 forbidden errors and then finally got two 500 server errors. They then came back and everything worked fine. Here is one of the 403s and two 500 error message from the logs:
[Sat Nov 27 13:30:37 2010] [error] [client 98.245.254.nnn] client denied by server configuration: html/store/prodpic.jpg, referer: [
domainname.com...]
[Sat Nov 27 13:30:37 2010] [alert] [client 98.245.254.nnn] .htaccess: RewriteCond: bad argument line '%{HTT', referer: [
domainname.com...]
[Sat Nov 27 13:30:37 2010] [alert] [client 98.245.254.nnn] .htaccess: RewriteCond: bad argument line '%{HTTP_USER_AGENT}', referer: [
domainname.com...]
I didn't see anything in my htaccess file that would account for this. The only thing I could think of was perhaps they were trying to hotlink the images. Would that cause this type of error?
