Caché Server Pages (CSP) is both an architecture and toolset used to build an interactive web applications with the InterSystems Data Platform.

Is there a way, for testing purposes at least, to change a CSP session over to a different user? We have a lot of things in our system that are allowed or restricted based on the user login, so it would be useful for me to be able to occasionally run as a different user to see how things look and work for them. I've tried using the %CSP.Session.Login function, but that still shows the CSP session as being from the original user, not the one I've switched to.

Cloudflare and CSP

Hi,

Has anyone experienced any issues when using Cloudflare in front of a csp application?

I keep getting 502 errors when Cloudflare is active?

Strangely, the SMP works but only if I remove the trailing question mark from the url but it doesn't resolve the issue when I try any other csp application URL's.

I have a CSP page that throw a "414 error - Request-URI Too Long" when I put lot of text (eg : 10000 characters) into a field of a submitted form. The form is submitted using POST method.

Based on some experiments I made, it seems the max size of a URL is around 8200 characters.

What is the official limit, and is there a way to increase it ? I searched in the documentation but couldn't find anything.

I was trying to add theater and time slot. But I was not able to do that.

I was also trying to filter the records as per the ratings and category selection on the search bar. but this is showing some error.

Why do I upload files faster with webservice than with csp?

The soap protocol used by webservice has to go through http protocol. csp directly handles http, no xml encapsulation, so it should be faster.

After testing, for a 1M file, csp is about 0.1s slower. After the gateway connection to 1972, there is a stall of about 0.1s, not sure why.

Is there any way to make the file upload speed of csp faster than webservice?

webservice用的soap协议也得走http呀。csp直接处理http，少了xml的封装，按理来说应该更快。

经测试，1M的文件，csp慢了0.1s左右。在网关连接到1972后，有0.1s左右的停滞，不知道原因。

Hello,

I'm using $ZF(-1) in a class method which will be invoked from a csp page.

What determines the environment of the spawned process? If I use $ZF(-1,"echo hello world > output.txt"), the resulting file is owned by cacheusr:cacheusr. However, when I use $ZF(-1,"printenv > output.txt"), the environment is from my personal unix account, no matter which Cache username I'm logged in under when running the web application.

Thanks

Dear Folks,

I have recently studied deepsee and developed few dashboards needed for our web app users. I am trying to embed them in our existing web app which uses angular with delegated user access. I need to embed the native IRIS dashboard into it. ( I can't use Highcharts or any other js tools).

How do I setup the dashboards to work with delegated authentication (Without providing access to management portal or other parts) ? Also should I use the default csp/{Namespace}/_DeepSee.UserPortal.DashboardViewer.zen? or any other web application URL ?

Thanks

Currently, I am working on a CSP application that is supposed to generate reports. Users will have varying access to said reports. To achieve that, I plan to use LDAP (because it's used in other systems where those users already exist). Documentation does not provide enough information, so I'd like a clarification:
Do I need to enable LDAP authentication for the whole Cache instance to use LDAP authentication in a single CSP application in that instance?

Hi All,
I am implementing REST API's in IRIS using the below link as a guide.
I chose this approach so i could have a single entry point for requests regardless of namespace

https://community.intersystems.com/post/restful-exception-handling

a sample form the HIHLib.REST.Server class i am using is below. my question is does IRIS and CSP cache responses for requests to the CSP.REST class?
and if so what parameters or properties do i need to enable?

Does anyone know how to get the closing tab/menu changing event in a CSP? I've tried the JS "OnBeforeUnload" already but it seems the browsers aren't allowing it anymore. I need to show a pop-up that holds the user if trying to get away before completing the stage.

Hi Community,

is there a possibility to implement a "remember password" feature in a ZEN Application?

In the management portal I added a web-application for a ZEN application with password authentification. I created an own login page, and now I want to implement a "remember password" feature (User should not have to login again after the session times out or when the browser window is closed).

Hey Intersystems Community,

I have a Problem with the Session Handling in .csp.

I wrote all my Web Services in .csp-Pages and do the work for example in the OnPreHttp Method for to get some data.

After that the Web Service response is in JSON.

I call These Web Services via fetch in my react Single Page application, also Many request parallel. The react App is Rolled out as index.html.
Everything Works Fine with the session Handling via Cookie.
