Hi,I am using haproxy 1.5.9 and apache 2.2.22 app servers behind it
I am trying to run some pen testing using burp suite pro on my application and 
this one issue keeps showing up "Frameable response (potential Clickjacking)"
I tried to resolve it by adding the following lines to the https frontend in my 
haproxy.cfg 
   rspadd Strict-Transport-Security:\ max-age=16070400;\ includeSubDomains
   rspadd X-Frame-Options:\ SAMEORIGIN
   rspadd X-XSS-Protection:\ 1;\ mode=block
   rspadd X-Content-Type-Options:\ nosniff

but it keeps coming back with the same vulnerability "Frameable response 
(potential Clickjacking)"
when i check my browser using firebug or developer tools i can see that the 
response header is set correctly

but when i check the reponse in burp suite i see 

HTTP/1.1 200 OK

how is that possible? can anyone shed some light
