Unexpected switch to HTTPS

[Horcrux7]

I start the JNLP application with the URL: jnlp://localhost/jnlp/designer?instance=SESSIONID80%3Dnode09qg5z107jsb68fekayxyfbv00

But OpenWebStart switch to HTTPS starting with the follow logline:

Candidate URLs for [l=http://localhost/jnlp/designer?instance=SESSIONID80%3Dnode09qg5z107jsb68fekayxyfbv00 v=null s=I]: [https://localhost/jnlp/designer?instance=SESSIONID80%3Dnode09qg5z107jsb68fekayxyfbv00, http://localhost/jnlp/designer?instance=SESSIONID80%3Dnode09qg5z107jsb68fekayxyfbv00]

On the HTTPS port the service is also running but the certificate does not match to localhost. That I have start it on HTTP (without S).

There is also no warranty that a service that run on another port is the same. If we want start via HTTPS then we use the protocol jnlps:. Why OpenWebStart is doing this? the certificate is wrong? How can we prevent it?

If OpenWebStart download the the JNLP file via HTTPS then the codebase use also HTTPS which is wrong.

Did you try the setting “do not favor https requests” ? Try to check this setting.

that may rather be a problem on the server side which renders the JNLP file.

This option solve the problem for me. But I think you should cancel the switch to HTTPS if the certificate is not valid. If the user starts with localhost there are many cause why the certificate can be wrong.

Why you think this is a server problem. If the client starts with HTTP then it continue with HTTP. The user will have causes because do it. If the client starts with HTTPS then the server continue with HTTPS.
