403 Errors if many requests within seconds
Posted on 2006-11-01
Hello, my server is really giving me a headache!
I have a webpage with about 100 peripheral files (JS, CSS, jpg etc.)
Many site visitors have been complaining that they receive 403 errors.
If you refresh the page too quickly, you will get a 403 error ALMOST EVERY TIME.
Refresh the page 5 times in a row and you will be sure to get a 403 error.
Sometimes only half the images will load, and the others will be broken because of 403 errors.
My theory is that the server thinks that my visitors are hackers because they are making so many requests within a second.
By the way, I don't get this complaint at all from dial-up users-- the faster my visitor's high-speed connection, the more likely they are to get a 403 error.
Here are some key settings from my httpd.conf
LoadModule expires_module libexec/mod_expires.so
LoadModule bwlimited_module libexec/mod_bwlimited.so
LoadModule bytes_log_module libexec/mod_log_bytes.so
LoadModule auth_passthrough_module libexec/mod_auth_passthrough.so
LoadModule evasive_module libexec/mod_evasive.so
Please help! Thanks.
