Synopsis
LimitRequestLine bytes
Default: LimitRequestLine 8190
This directive sets the number of bytes
from 0 to the value of the compile-time constant
DEFAULT_LIMIT_REQUEST_LINE (8,190 as distributed)
that will be allowed on the HTTP request line.
The LimitRequestLine directive allows the server
administrator to reduce the limit on the allowed size of a
client’s HTTP request line below the normal input
buffer size compiled with the server. Since the request line consists
of the HTTP method, URI, and protocol version, the
LimitRequestLine directive places a restriction on
the length of a request URI allowed for a request on the server. A
server needs this value to be large enough to hold any of its
resource names, including any information that might be passed in the
query part of a GET request.
This directive gives the server administrator greater control over abnormal client-request behavior, which may be useful for avoiding some forms of denial-of-service attacks. Under normal conditions, the value should not be changed from the default.
