Currently we have some servers that are going to give service to a certain region, thus they have their own unshared users, although we need to establish a secure connection in order to make the site function correctly.
By now we only have one single domain SSL certificate that permits just one site function with https and we are looking for the best cost effective solution by spending the less in certificates and extra servers in order to offer a HTTPS connection to all of our sites.
Is it possible to establish many HTTPS connections to different sites located on various server only using one UC Certificate ?
- Windows 2003 Servers (latest SP) X 3
- IIS 6.0
- 1 public IP
- 2 regional sites (Ex: North America site / South America Site )
- RIA App
- A single IIS can not contain all the websites
- Sites are separated to offer better application performance
Proposed solution #1: Make an IIS 6.0 server a reverse proxy
With this approach I think the user could access the site and the application easily although I am concerned about how the SSL would behave and also if there could be problems because the site is a RIA.
Proposed solution #2: Use IP aliasing or NAT
Although the article was about Linux and Apache, I think a somewhat equivalent solution could be given using NAT to redirect the user to the correct site. Once again my main concern is that the HTTPS connection could fail.
Proposed solution #3: Virtual directories
This one seems interesting although I do not see it as practical because what we really want is to separate the distinct sites and not make one server that runs all of them.
Proposed solution #4: Use a load balancer
This one seems as the most obvious solution, although I want a more static solution, and also I would like to see how this works with HTTPS.
- We can buy the UCCert although we would prefer not to
- Can we use a single domain cert to accomplish all that?
- How will ASP sessions would be handled by this setting?
Thanks a lot for your time and a lot more if you can contribute in some guidance over how to make the best choice.
