If a connection to
httpd(8) is causing congestion on a network link, one can drop the TCP session in charge:
$ fstat | grep 'httpd.*internet.*<--'
www httpd 21307 3* internet stream tcp \
0xd1007ca8 192.168.5.41:80 <-- 192.168.5.1:26747
The following command will drop the connection:
# tcpdrop 192.168.5.41 80 192.168.5.1 26747
