Hi,
Just want to have a better understanding on request header. My server
seems to have a lot of 'request header too large' and I am wondering if
there is anyway to confirm whether it's due to dos, buffer-overflow or
bugs.
Is there anyway to log the request header to investigate? I tried using
log_mime_hdrs, but I cant tell much from it...
2002/08/23 10:41:34| Request header is too large (24575 bytes)
2002/08/23 10:41:34| Config 'request_header_max_size'= 20480 bytes.
# TAG: request_header_max_size (KB)
# This specifies the maximum size for HTTP headers in a request.
# Request headers are usually relatively small (about 512 bytes).
# Placing a limit on the request header size will catch certain
# bugs (for example with persistent connections) and possibly
# buffer-overflow or denial-of-service attacks.
Rgds,
Wei Keong
