OHS SSL Request LimitRequestFieldSize Directive Ignored and Header Request Size Unknown (Doc ID 2391162.1)

Last updated on AUGUST 03, 2023

Applies to:

Symptoms

OHS ssl.conf LimitRequestFieldSize directive configured to set the number of bytes allowed for HTTP request headers to be larger than the default, 8190 bytes, for SSL requests.

However, the $DOMAIN_HOME/servers/<ohs name>/logs/access_log shows HTTP status 400 (Bad Request) errors.

The access_log does not capture the request header size sent; therefore, it is unclear if LimitRequestFieldSize limit is exceeded, and it is not known to how to test LimitRequestFieldSize.

Changes

OHS ssl.conf edited to include LimitRequestFieldSize.
