Web Server - Ask For Help / Webserver performance slow after restart
« Last post by TimR on July 22, 2025, 01:35:37 PM »I'm having an issue with a webserver when it restarts where the performance is painfully slow. To set the scenario, I have a powershell script that runs and monitors that the webserver is running, it checks every minute. If it isn't running, it starts the webserver. After the restart the webserver responds to requests very slowly, until I shutdown the webserver for 10-15 minutes (timeframe is approximate), or restart the server. Database is MSSQL with some topspeed files. Has anyone else experienced this behavior and even better figured out a cause

Web Server - Ask For Help / Re: Problem running from localhost
« Last post by rjolda on July 19, 2025, 11:15:35 AM »Hi Richard,
Localhost (127.0.0.1) is a loopback address on the local machine.
Port 80 is generally reserved for http server running on the machine. Typically, IIS or other web server runs on port 80.
So, do you have something like IIS running on port 80. Connect your local browser to http://127.0.0.1 and see if it is running something - if it is, then you will have a problem. Actually, Net talk should tell you if it can't run on a port. E.g. if you had IIS web server running on port 80, net talk app should tell you it can't run on port 80 and it should tell you.
I would suggest that you go away from port 80 and to to port 88. (your browser can remember that!).
There are network commands to play with 127.0.0.1 but I doubt that you executed any of these.
You can read up on loopback IP addresses here: https://dev.to/leapcell/understanding-network-interfaces-loopback-local-ips-and-public-ips-2p47 and https://www.geeksforgeeks.org/computer-networks/what-is-a-loopback-address/
Hopefullly this will give you some insight and some dos testing of your local ports.

« Last post by Richard I on July 18, 2025, 06:34:25 PM »Hi Jane,
I have isolated the problem to PORT 80( which is the local PORT I routinely use) by running a webserver example using PORT 88 The example ran perfectly, and on changing the Port to 80 caused the now familiar error.
Using PORT 88 in my app also was succssful.
The running application now on PORT 80 is elusive, surviving Shut Down.
How can I discover what it is? as Ive searched Task Manager and got the syntax for Powershell from AI both without success.
Thanks for your contact and help
Cheers
Richard

and in nedtdemo using client 127.0.0.1
on connect the error message is
<a netwoprk communication error has occured.
Error= - 53 which means Open Timeout or failure error{winsock error = 10061:( WSAECONNREFUSED) Connection refused.No connection could be made because the target machine actively refused it.]
Error occured in functionm NetSimple.TakeEvent>

If you copy the address from the browser address bar and paste it into notepad, to you see http:// or https:// ?
Also try compiling the netdemo program and use its web client to verify that you can connect to your app with http

I was tripping between C12 and C11.1 on the same PC when, following a successful compile and run, on opening the Browser using localhost:80 or 127.0.0.1:80 I get this error-
<localhost uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.>
I have NO idea how to resolve this, so would appreciate help

Web Server - Ask For Help / J Files Question
« Last post by rjolda on July 14, 2025, 02:11:51 AM »Hi,
I am just starting to play with J Files. J files 3 and CLarion 11.0 ABC.
I have a master table which is a collection of initialization records for each of my kiosks.
I want to be able to write the record for only ONE kiosk to a json object so that I can re--import it to a new computer in that kiosk.
I played with the basic:
json.Start()
json.Save(KioskTable,'.\Kiosk.json')
This make it effortless to place all the Kiosk records into the Json object.
HOWEVER, I want to pick and export ONE record.
How can I placr a filter so that only 1 Kioskrecord that I have chosen gets written to the Json object?
Thanks,
Ron
