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

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...

Hi everyone,

This is:

Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.2 (Build 736U) Fri Sep 30 2016 12:25:56 EDT

The server is on RedHat Linux while the browser is running on Windows (Firefox).

I am helping a partner build a complex modern HTML5 web application that talks with Caché using REST calls. They have been using %CSP.REST very successfully. Security works great as well.

Hi-

I am trying to create a simple example of allowing binary (tiff) files to be selected and uploaded asynchronously to an IRIS for Health back-end. I have managed to write the HTML and Javascript which works great with regular text / ascii files, but fails with binary files.

When I upload a binary file (tiff) image I get garbage like this on the database server

CSP Error Log

I thought I should be able to go to the application error log or look at d ^%ER when I get the following error in the browser when troubleshooting a CSP page:

An error occurred with the CSP application and has been logged to system error log (^ERRORS)

However nothing is being generated in these logs. Where are these logs being made?

Thank you

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.

Hello Community,

I recently encountered a issue with Caché and I can't figure out where the problem is coming from.

I noticed that the license limit (200) was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after. The time taken before the number of license grows back again looks pretty random.

Here is a couple of screenshots :

$fromJSON and MAXSTRING

Hi, all.
I have CSP application and it needs to get and process data from ajax request with json-content. JSON can be very big.
In this case:
TRY
{
Set RequestObj = ##class(%Object).$fromJSON(%request.Content.Read())
} CATCH(Exception) {
Set Status=Exception.AsStatus()
}
I get just part of getting JSON and validate error in $fromJSON.
If I try to read it all in cycle:
TRY
{
While (%request.Content.AtEnd = 0) {

Hi!

I am not system admin. But it used to be very simple to install CSP Gateway on an apache system on Linux with Apache installed. I used to run the CSP Gateway installation program and after it was done, all I had to do was fine tune some configurations on CSP Gateway portal on http://<ip>/csp/bin/Systems/Module.cxw and I was up and running.

Hello,

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

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

I followed the configuration guide (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...) 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:

Hello, I'm trying to install CSP Gateway on Ubuntu 18.04 (Apache) with the installer CSPGateway-2018.1.1.638.0-lnxubuntux64.tar.gz but it doesn't seem to work. I keep getting access-denied when I try to open CSP-pages or the CSP Management portal.

Does someone have an installation-manual or so ?

Hi


I have been working on changing a web application from using %FileBinaryStream to storing and serving the file content from a %Stream.GlobalBinary property, stored in a new database. I have managed to migrate the data across, and have also been able to redirect the stream so that it is being served through the web link. However, the previous method set attributes on the File stream to have the stream be rendered as the original file type through MIME, using this code

We are currently looking into a way to provide a group of end-users (i.e. non-Interface Development engineers) access to a pre-defined group of Ensemble-based Data Lookup Tables for purposes of viewing and editing. We do not want to give them access to ALL Data Lookup Tables due to security/continuity concerns.

My thinking is that a simple persistent Cache table with three columns (Role Name, Table Name, Access-Level [like View or Edit]) with a CSP front-end could potentially provide an easy way to make this solution a reality.

在Aix7.1上安装使用root用户安装cache2016.1.1.107，且在安装过程中创建cacheusr用户；更改操作系统上的cacheusr的umask后，通过数据库修改编译后的文件(如，js，csp等)在小机上查看权限不变（-rwxrw-r-- cacheusr cacheusr test.js）。

目的：通过数据库编译后的文件的other用户有读写权限。
