Yes

Use SSL: http://it.toolbox.com/blogs/securitymonkey/howto-securing-a-website-with-client-ssl-certificates-11500

Or use Nginx as a reverse proxy to Cheyenne.

So, I don't need Apache then?

I'm currently using Cheyenne ... and stunnel to provide SSL

Looks like I could still use stunnel .. and put all the certificates 
in a directory and disconnect users who don't present a certificate

I might have a few hundred users ... so hopefully this can cope.

So, I guess I'm asking if anyone has experience with this and was 
it straight forward?

Hundred users total, or concurrently?

total

I'm looking to implement a nationwide registry for patients taking 
biologics

Shouldn't be much of a problem performance wise

worst case scenario - 60 concurrent users

How many requests would they make within a minute?

I wouldn't have thought that many ... of course I'm just guessing!

Well, that determines your scalability concerns

60 Concurrent users is a lot - except if they're idling for five 
minutes between every request

I guess I can just get a bigger VM if it comes down to it ... :) 
 Yes, I expect they'll be idling most of the time

So, I guess the next question is .. how does one determine if the 
server is overloaded?

read the logs and ??

Your customers will be on the phone yelling at you :-)

If it's a Unix box, you use tools such as uptime, top and htop

Windows 2003 server on Ec2

I gave them my cellphone so they can pay the charges for yelling 
at me!

heh... the freemed guy was asking if I can rewrite my drug interaction 
portal in php and python!

Hmm... can Magic on Apache run similar RSP code as Cheyenne ?  Wonder 
how hard it would be to port from Cheyenne to Magic

Magic!'s concept is the reverse of RSP

reverse?

I've never used it ... just know it exists

Dockimbel can give you advices.

There's QM from ChrisRG but not sure it reached a official release.

True and that uses Apache

This is the app I'm working on to deploy nationwide ( small nation 
though :) ) https://nzra.cloud-ehr.net/

There's a Guest account

Now if a certain big pharma company goes ahead to pay for this as 
they have said .. I'll put "powered by Rebol" banners everywhere 
:)

And Powered by Cheyenne banner !

that's already ther e...

everywhere !

;-)

RSP is a template system. Magic! generates pages from REBOL dialects

Graham, if you're concerned about performances and scalability, I 
don't understand why you're considering a CGI-based solution? AFAICT, 
Cheyenne/RSP is the most scalable solution for running REBOL code 
on server-side. If a single Cheyenne instance is not enough, you 
can use a nginx front-end to server static content and dispatch the 
load over several Cheyenne instances.


Our biggest online web-app has ~800 users, with several hundreds 
logging in each day, accessing a 400MB RDBMS with millions of records 
served by a single Cheyenne instance, with 8 workers (each taking 
15 to 25MB of RAM) running on a 2.2Ghz DualCore CPU with 2GB of RAM. 
Average Cheyenne load is 2 req/s with peaks up to 100 req/s (usually 
caused by web scanners or attacks). The webapp is still performing 
well under these conditions, and we have plenty of space to improve 
performances when it will be required (with faster hw and more instances).


Also, a key factor is optimizing webapp's code, especially for the 
most used RSP pages. Btw, a profiler would be a good addition to 
Cheyenne/RSP framework.

Cool

Great, I was sure that Cheyenne can do it !

Doc, it wasn't me .. it was these other guys who wanted to use this 
thing I'm writing where they don't have the option of installing 
Cheyenne.

They also asked me to port to python and php ... lol

One version in Python and one version in PHP?

I guess so ...

Given this JS

					if ( bValid ) {

       var dataString = 'pain=' + pain + '&ptgl=' + gs + '&fn=' + fn + '&rapid3=' 
       + rapid3 + '&fatigue=' + fatigue + '&ros=' + ros + '&ems=' + ems 
       + '&patient=' + '<%=patient%>' ;
						//alert (dataString);return false;
						$.ajax({
							type: "POST",
							url: "add-rapid3.rsp",
							data: dataString,
							success: function() {
							 	// removed ...
							}
						});
						return false;
  
						//$( this ).dialog( "close" );
					}
				},

what would cause this?


28/12-23:58:37.055-[DEBUG] c: [pain "[object Object]" ptgl "[object 
Object]" fn "[object Object]" rapid3 "[object Object]" fatigue "[object 
Object]" ros "[object HTMLInputElement]" ems "[object Object]" patient 
"7"]

where the add-rapid3.rsp is

<%
	; add-rapid3.rsp
	c: request/content
	?? c
	exit
%>

guess my javascript is screwed somewhere ...

This is a result of not overriding the default toString() method 
in your pain, gs, fn, rapid3, fatigue, ros and ems objects.
