Using stunnel + haproxy for SSL support

 Hi,

I'm having trouble using stunnel and haproxy to load balance https and http traffic. To be honest, I really don't know wether it is stunnel or haproxy related so I am going to contact both lists :)

I have set up a haproxy load balancer as http proxy for two backend Apache2 webservers. It works fine.
I also have stunnel on the same LB to add SSL suport (with xforwardedfor patch installed). It works fine (mostly).

The issue is related to Apache trailing slash thingie. If I query https://haproxy.domain.loc/hatest/ it works perfectly, but if I omit the trailing slash: https://haproxy.domain.loc/hatest then following things happen:

• Browser makes SSL connection with stunnel on port 443.
• stunnel deciphers and forwards the request on the haproxy attached to LB's port 80.
• haproxy (now using plain http) forwards to one of the backends.
• Apache2 located on the backend replies with "301 moved permanently" to force the browser to add the trailing slash. As Apache was queried by *haproxy in plain http*, the 301 includes http:// on the Location header. HTTPS is over from now!
• The client browser then rewrites the address to http://haproxy.domain.loc/hatest/ and SSL is lost forever.

I've been googling and searching the lists but nothing found. There is any way to fix this?

Thanks in advance.
