RE: Redirect to HTTPS using Load Balancer/SSL Offload

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 





You could use a wildcard SSL cert and redirect to https://secure.*.tld:/patcha/patchb/file then make your determination based on the hostname.

The extra $100 cert is a lot less expensive than Radware AppXcel for sure.

Eric,

That definitely seems like the reason the redirect keeps looping.  Every
example I have seen has involved {SERVER_PORT} (is or isn't) 443 as a
RewriteCond, but I haven't found a way to let apache know if the current
session between the client and the load balancer is being encrypted or
not.

Brian,

I am using a Barracuda, which is far cheaper, and has far less features
than some of the other vendors like Radware, F5 and Cisco LocalDirector.
I will find out if it there is a way for the barracuda to let apache
know its current offload status so it can differentiate between each
request.

Matt

Radware has some nice header rewriting features in its SSL accelerator
package.

Thanks for the reply.  The redirect loops the requested page never
comes
up.  The log prints the same thing over and over.

You said the LB does SSL offload. You haven't given apache any way to
distinguish when someone hits the LB via http or https, so it
redirects in both cases.    Maybe your LB sets some additional header
in the case it handled SSL?
