A Tutorial On WebSockets

Intro

Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.

In the WRC, we frequently see customers contact us because their Web Gateway is unable to serve web pages. This article will explain a frequent reason why these errors can occur, and explain some tools which can be used to debug the problem. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

Hi Guys,

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

We recently moved from using the Private Web Server, to using an Apache/Web Gateway setup and moved towards using the built in LDAP functionality within IRIS. Since then, we have 1 user that uses VSCode (/api/atelier) heavily that continues to have issues signing into IRIS through VS Code and the /api/atelier extension.

I am trying to troubleshoot two issues..

We tested REST Services as described for Caché DocServer example and for requests using http protocol it works without problems. However when we use the https protocol for the same REST Service it is not available. Our infrastructure is as follows: Apache with openssl, which works on the other hand well for CSP with https. If we switch on the web gateway http trace facility we could see the request of CSP pages by https://... but again a request of a REST Service by https:// will not result in a entry in the tracer. We hope that this description of the problem is understandable.

In the WRC, we often see customers raise questions regarding a new Web Gateway setup where the Management Portal half-loads, but doesn’t show images. This article will explain why this error occurs, as well as how to fix it. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

After what is seemed was weeks, I finally got SSL/TLS enabled on both Apache Web Server and IRIS using the Web Gateway. However while we can now use HTTPS to connect to our Development instance of IRIS, I am running into several errors when I have others try to access the Management Portal via HTTPS.

We are seeing...

Hi All,

I hope someone can help me with the following, it's about the usage of the class EnsLib.HL7.Service.HTTPService.

Working situation right know.

In IIS we've got a site configured who is dealing with the client certificate, etc and redirect the full request to http://localhost/csp/healthshare/NAMEPSACE/EnsLib.HL7.Service.HTTPServic... and the web gateway redirects the request to Business Service 'EnsLib.HL7.Service.HTTPService.cls'.

I am not sure if this is the correct place for this question, but I am struggling to setup TLS security for our IRIS Management Portal and etc. through Apache and the Web Gateway. I have a couple of questions when it comes to the setup.

  • if I build a private key and certificate within Red Hat, does that certificate have to be on everyone's pc to connect to the Management Portal?
  • Can I use a self signed Certificate?
  • Can I use the existing CA on the server, or do I need to work with my Data Security team to get a Certificate?

Running HealthConnect 2021.1 on RedHat Linux 8.4.

I've configured IRIS/HealthConnect with an external web server to support TLS encryption. It's installed on the same server as IRIS, but is a different instance and version of Apache httpd. That all works as expected.

I would also like to keep the "private" web server available, but I'm having an issue with using the fully-qualified domain name in the URL vs. just the hostname itself.

If I use http://servername:52773/csp/sys/UtilHome.csp to log on, all is well.

Hi all!

I'm currently trying to find out how to have one Web Gateway route to multiple servers Management Portal. The only thing that I have come up with so far is to potentially make different routes per server?

I have a development, test, and production server and I want to use the same Gateway server using IIS to do SSL/TLS encryption for the CSP pages.

Any ideas or recommendations to pull this off?

Prerequisites

Make sure you have git installed.

I created a git folder inside the IRIS mgr directory. I right clicked the git folder and chose Git Bash Here from the context menu.

git clone https://github.com/oliverwilms/csp-log-tutorial.git

Clone my csp-log-tutorial GitHub repo if you like to try it out for yourself.

I am using the event logger from CSP gateway with level "v9r" enabled, in order to dump the raw content of some HTTP requests.

I would like to decode the body response data, when it's in binary form. AFAIK the event logger will convert characters outside the 32-127 range (EBCDIC) to the "\xff" notation (where ff is a hexadecimal value). Here is an example :

This is probably not the right place, but I don't know who I can reach out to... I am trying to configure an Apache/Web Gateway to our instance of IRIS so we are no longer using the built-in PWS. Can anyone point me in the right direction to configure Apache/Web Gateway to repoint

http://<server name>:52773/... to the https://<server name>/...

gateway so our users will not notice? How do I do this in Apache, do I need to modify httpd.conf or the ssl.conf file? What is the correct syntax...

You may have already heard that, starting with IRIS and HealthShare HealthConnect 2023.2 versions, the internal Apache Server will be removed from the default installation, so it will be necessary to have an external application server such as Apache Server or NGINX.


In this article I am going to proceed to install a HealthShare HealthConnect 2023.1 so that it works with a pre-installed Apache Server. For this I will use a virtual machine on which I have installed an Ubuntu 22.04.

InterSystems FAQ rubric

You can set individual error pages for the following Web Gateway error messages/system responses:

  • server error
  • server busy
  • server unavailable
  • server timeout
  • connection closed

Settings are made on the Web Gateway Management screen ([Management Portal] > [System Administration] > [Configuration] > [Web Gateway Management] > [Configuration] > [Default Parameters]).

In the Error Page section of the Default Parameters menu, set the filename of the html page to display or the URL to redirect to when an error occurs.
