In my headers, the "HTTP_KEEP_ALIVE = 300" is not displaying and I'm not sure why. I have the following header_access rules: header_access X-Forwarded-For deny all header_access Proxy-Connection deny all header_access Via deny all header_access All allow all With these rules I get the following headers: HTTP_ACCEPT = image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */* HTTP_ACCEPT_ENCODING = gzip, deflate HTTP_ACCEPT_LANGUAGE = en-us HTTP_CONNECTION = keep-alive HTTP_COOKIE = __utma=131785806.1971945049.1220944678.1221168849.1221173272.5; __utmz=131785806.1220944678.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none); __utmb=131785806; __utmc=131785806 HTTP_HOST = www.proxyjudge.biz HTTP_REFERER = http://proxyjudge.biz/ HTTP_UA_CPU = x86 HTTP_USER_AGENT = Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727) REMOTE_ADDR = XXX.XXX.XXX.XXX REMOTE_PORT = 51600 REQUEST_METHOD = GET REQUEST_URI = /az.php I have even tried removing all the header_access rules except for header_access All allow all. However, HTTP_KEEP_ALIVE = 300 does not display. I am using Squid Version 2.6.STABLE6 on Red Hat Enterprise Linux 5. Any help is appreciated, thanks.
