the short answer is yes -
but I'm not sure you asked the question you meant to ask.

Perhaps explain a bit more about what you have in mind?

cheers

HI

"Load Balancing" usually refers to the spreading of sessions across multiple web servers.  Windows provides NLB (Network Load Balancing) which performs this function but there are other hardware implementations that incorporate high availability and extended performance options.

In this environment the Clarion-NetTalk program can run on multiple servers with say, a single database server and therefore can work in a load balanced environment.  You won't have to do anything special in NetTalk to take advantage of this technology.

But maybe this is not what you meant.  Perhaps you meant controlling or balancing individual sessions on a web server.  That is another question that would require more specific information to address.

Hi,
This sounds very interesting.
Has this been discussed somewhere before?

we've chatted about load balancing a few times in webinars and so on.
Typically it isn't actually all that interesting unless you have a server that cannot cope with the incoming traffic.

The short answer is that Load Balancing a NetTalk server is no different to load balancing any server, and there are lots of tools out there that can assist with doing that.

cheers

Hi,

We load balance our big NetTalk Servers.

We have load balanced in AWS. You can use ELB (AWS's built-in load balancer).

We have load balanced with our Fortinet routers.

Under some circumstances you need to do extra stuff in your NetTalk app.

For example, if you want to support both HTTP and HTTPS traffic on your site, but also offload SSL to your load balancer, AND you also need to redirect HTTP requests to the secure part of your site, you need to read the special request headers to work out if you need to redirect to HTTPS or not.

Further John Moore who works for LJ Hooker in Australia has also built a load balancer in NetTalk. They use that in production at the moment.

Regards
Bill
