I am writing an API that sends over a very large JSON object.

The code I'm using to get the data is actually used in our production system today for the use of writing a report.

However when I call the code using the API (using SoapUI) I am getting 'Error getting response; java.net.SocketTimeoutException: Read timed out'

The web applications settings have a session timeout setting at 15 minutes, but this is timing out within just a few minutes, so I know it's not hitting this mark.

Hello,

I have a couple of IOT devices that communicate via WebSockets to our backend.

I successfully managed to create a websocket connection between server and (iot)client using %CSP.WebSocket
However I would like to implement authentication on this using the HTTP headers at the same time of Connection: Upgrade.

I tried to set the headers to globals in order to debug but they are always empty.

Example code:

Hi developers!

I just want to share with you the knowledge aka experience which could save you a few hours someday.

If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all' don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.

/patients

- will work, but

/patients/all

- won't.

Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:

    <CSPApplication Url="${CSPAPP}"
      Recurse="1"
      Directory="${CSPAPPDIR}"
      Grant="${RESOURCE},%SQL"
      AuthenticationMethods="96"
      />

Pretty straight forward.

I'm tempted to hard-code ISO-8859-1 inside my VSCode extension when working with CSP because this seems to be the encoding used by default, but I need to know if there's any other possible configuration. So can you share your experience when working with CSPs? Like issues with encoding, discoveries regarding it, workarounds etc.

Also, can someone tell me if it's possible to work with UTF-8 encoded CSP files using Atelier without breaking the encoding of the output file?

Hi All

I this article I detail some strategic issues that a new development UI will need to address - these are the ones that I can think of now - others may come to light during this journey.

See the webinar by Eduard Lebedyuk here from the last Global Summit describing modern web development and Caché

And, as always, if I have missed something please comment....

Here is an ObjectScript snippet which lets to create database, namespace and a web application for InterSystems IRIS:

    set currentNS = $namespace

    zn "%SYS"

    write "Create DB ...",!

    set dbProperties("Directory") = "/InterSystems/IRIS/mgr/testDB"
    set status=##Class(Config.Databases).Create(dbName,.dbProperties)
    write:'status $system.Status.DisplayError(status)
    write "DB """_dbName_""" was created!",!!


    write "Create namespace ...",!
    set nsName="testNS"
    //DB for globals
    set nsProperties("Globals") = dbName
    //DB for routines
    set nsProperties("Routines") = dbName
    set status=##Class(Config.Namespaces).Create(nsName,.nsProperties)

Hi, I have used CSP to exec SQL selects from any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

CSP Webpage:

TEXTBOX: Introduce your select:

Hello, has anyone tried to use Caché as a reverse proxy ?

We are trying to embed a dashboard server (Plotly Dash in this case, but it could be anything which runs on its application server) inside our application which is written in Caché.
The dashboard/report server runs locally (for example, or inside a LAN) on port 8080, and has no authentication features, so we have to implement them on a different layer, and we'd like to use Caché for it.

Anti CSRF Methods

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)

Non CSP Files

CSP pages extend %CSP.Page. What about html/css/js/etc that are hosted on the same web application? Is there any way to override how they're processed like with how you can override a CSP page and CSP REST logic?

Thank you!

Hey Intersystems-Developer,

I have already used that and know its possible, but can't find it anymore :(

I need dynamic access on proxy objects. For example:

set key = "lastName"

set name = obj.name

set lastName = obj.key <- Not possible

set lastName = obj.GetAt(key) <- Not possible

How can I get access to that object with my dynamic variable "key" ?

Best regards.

On one of our servers, when I am in Mgmt Portal and click the link for Configure / CSP Gateway Management, I get this url:

http://ipaddress.of.server:port/INSTANCENAME/csp/bin/Systems/Module.cxw?CSPSYS=0&CSPSYSreferer=_CSP.Portal.Home.zen

but the page displays a 0, and nothing else. Literally, just a 0. This link works on our other servers, with the same URL. Any idea why?

Thanks,

Laura

Hello,

I'm trying to set up an Apache server using CSP Gateway on Windows 10 (64-bit), but am getting the error "Cannot load c:/InterSystems/IRIS_2019/CSP/bin/CSPa24.dll into server: %1 is not a valid Win32 application" when attempting to start up httpd.exe after adding the CSP-specific section to httpd.conf.

The CSP gateway is 64-bit (CSPGateway-2018.1.1.643.0-win_x64) and so is the Apache install (httpd-2.4.38-o102q-x64-vc14).

The CSPa24.dll file does exist in the specified location.

Any suggestions appreciated.

Thank you,

Olga

Client Websockets based CSP

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

This is a quick note on what happens when, on your CSP page, you call a cache script which returns a %Boolean and store that value in a javascript variable.

When you call a script with language="cache" and returntype="%Boolean" from a javascript script, the return value is interpreted as a string, not as a boolean.

Here's an example:

A cache script that returns (in theory) a "false" value:

Looking for work

Hi every body

I hope it's the right place & I'm not offending any body.

I'm a veteran Mumps/Cache/Ensemble programmer . I think my only draw back is my age, although my brain is still young & bubbly.

I'm looking a long time for work without success.

I gathered a lot of knowledge & experience during those long years , developed many projects & i'm ready to do any work only to feel useful.

I'll add my resume, I hope & wish that this post will bring some change as I'm desperate to get some work.
