Hi, In one of my setup, I failed to loadbalance a fortiweb WAF protected website. Haproxy return 502, but the browser works OK.
With the help of wireshark, I notice that the response header returned by fortiweb WAF is not RFC compliant: HTTP/1.1 200 OK Date: Mon, 30 Dec 2013 05:40:02 GMT XXXXXXXXXXXXXXXXXXXXXXXXX MicrosoftOfficeWebServer: 5.0_Pub XXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXX Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 73803 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> ...... But browser(IE&Firefox) works OK. Can haproxy improve to works smoothly with such security appliance? BR, DetaY
