Subject: - added -r option to generate random Range requests. Ranges break
X-Git-Tag: SQUID_3_0_PRE1~3174
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c4248266bf7cca0772ecb73d10ee5e568aa34ab8;p=thirdparty%2Fsquid.git

- added -r option to generate random Range requests. Ranges break
  Content-length checks so the checks are disabled with -r option.
