Using the CSP Gateway is there a way for an web application to mimics MLLP sockets connection? I have a requirement for no PHI in the DMZ and I wanted to see if there is a way to install the CSP Gateway in the DMZ to received inbound/outbound messages where the DB is in the protected zone.
In our last lesson, we implemented a new REST Service to allow us to perform CRU operations on Widgets, and refactored our Controllers to allow the page setup to be decouple from the content.
In our last lesson, we implemented a linkage to our WidgetAccessory class, and debugged some errors we encountered along the way. We now have our data being returned by REST, but what if we want to update or add new data to our application?
In our last lesson, we added a relationship between 2 persistent classes. We are clearly going to need to start creating REST Services to expose CRUD operations for each of these classes, but before we do that, we should really finish defining our linkages. We added code to our Widget toJSON to spool off related Accessory data, so we should really do the reciprocal and allow Accessories to return all Widgets that are compatible.
We left our application over the weekend, secure in the knowledge that it was returning data from our primary persistent class, User.Widget. However, Widgets Direct are the premier supplier of both Widgets AND Widget Accessories, so we should really start working on adding these Accessories to our application.
We are using the InterSystems cache 5.02 We having 80 license unit but don't the reason 50 unit have been consumed (CSP unit) This happen because of this page ran frequently "/apps/docmatic/%CSP.SysConnection.cls" Can anyone explain why this page ran frequently and consume license?
or "Didn't you say you would cover Persistent Objects in Part 5, Chris?"
Yes, that was the plan. This is a pretty important topic, so it get's its own Article
Up until now, we've display widget JSON that has been created by a basic loop. Clearly this isn't of much value. Now we have our stack connected together, and we can see that the data is flowing to the Welcome page, it's time to complete the stack and start feeding our service from "real" data.
At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards. Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list. What can we do to help?
So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.
There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.
This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.
We finished our last lesson with our Widgets Direct page iterating over a list of widgets, displaying an ID and a Name value. While we have been able to achieve this with only a small amount of coding, the page itself is not the most visually appealing place to be. The AngularJS framework is providing a powerful Model-View-Controller framework for our structure and logic, but it does not implement anything that will provide a nice UI experience.
WebSockets look to be supported reasonably well in Cache. I have yet to use them in production so I am wondering how well it has worked for other developers.
In particular what happens when the browser does not support WebSockets, or when a firewall blocks the connection.
Have you had to write your own long polling fall-back?
I've read the documentation and found this interesting article...
We finished our last lesson with our Widgets Direct page receiving a Welcome message as a property of a JSON object, which was unpacked and displayed on the page. However, we are on Lesson 3, and we still haven't had any talk of displaying widgets yet.
In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.
You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.

In this recent post I highlighted the importance of a CSP session's Key property in enforcing the level of security your web application may be relying on, and in particular the need to keep the property value secret.
We are using an F5 load balancer to route public traffic to our IS server. My goal is to block public access to the Management Portal, and only allow what we want to expose, such as REST/SOAP services. At the F5, they can block URL wildcards or specific ports, so those are our options.
Since the URLs for the web services are in the same path ([host]/csp/healthshare/[namespace]/*), I can't see any URL wildcards happening. That leads me to ports; is there a way to put services on a specific port for all services, and everything else stay on a standard web port?
Sometimes when I have Zen page in a browser (e.g. Management Portal page) and when my Internet connection interrupts, I see the alert window on the page, something like this screenshot:
Is there any setting for the CSP web app to prevent this alerts from popping up?
Maybe someone has a logger for incoming CSP requests and willing to share? Debugging high traffic HTTPS application and wireshark just doesn't cut it sometimes. So I thought I'd ask here. I'm especially interested in getting raw stream of incoming request.
I have a 100% ZEN application combined with 100% ZENReports and am also using IFind which is part of the solution.
Our application is a cloud hosted solution where we lease a server which does not have a website, only Cache configured under IIS. Connectivity to our site is premised on a URL string such as u12345.usa-server.com/csp/namespace/Cache.cls
We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.
We are ready to re-write the code in Zen also if it supports that feature.
Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.
Hi All,In CSP how to call one method to another method (i.e) i created one script language as cache from that one script to another script that one also a cache script ,how to call the script.
If you are developing applications that use CSP or Zen, or potentially any of the other InterSystems web-related stuff that's built on top of CSP, then it's important to know how to keep one particular secret.
A central part of the CSP security architecture is a server-side session key. "Server-side" because its value should never be revealed to the client that is issuing the web requests. If it is revealed, a malicious client might be able to use it to bypass your security and make your server do things you don't want it to.
So I installed Atelier, created my project, imported and compiled all my classes but now I need to import all my CSP files too but I can't find any instructions on how to do so. Just copying the files into [project]\CSp\csp is not working as they don't show up in the project tree.
I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL. Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.
Suppose you have developed your own web app with InterSystems technologies stack and now want to perform a captcha validation on the client side in order to determine whether or not the user is human and make it safer. There are some modern frameworks to address the captcha issue, however most part of them needs internet access to generate codes and sometimes are complex to implement. Take this as basic example considering that image recognition has gotten too good. That's why you nowadays you tend to see more pattern recognition captchas than mere reading ones. (I.e.
We've found that in most cases when we open a new CSP session the CGI varaiable %CGIEVAR("HTTP_COOKIE") contains the client name.
It looks like that : "state=SYSADM%3A0; Username=Urish; CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11..." In some other cases this CGI only contains $zv - like "CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11 2013 23:20:33 EDT"
Is there any simple way to fetch the data directly from the database (using the URL and credentials) from the csp file without creating a link table for that particular Table...??
If there is, could you please share the syntax of using them ..?
Can we have an object return type from the below mentioned method to a javascript function.. ???
