Dear team, how can i open the osimis viewer programatically adding the user/password when the server requires authentication?
This to avoid to enter the username/password manually.
Thanks in advance.

Well, it’s just basic HTTP auth so you can pass the login/pwd in the url: [http://username:password@example.com/](http://username:password@example.com/)
Usually, at this time, you realize that you just don’t need authentication if you try to bypass it 🙂

Actually we can’t rely on passing basic auth in the URL as most modern browsers will block it.
[In version 1.3.0.0](https://www.osimis.io/images/wvp%20release%20notes.txt) Osimis had a change regarding this question:
_Query arguments (i.e ?token=1234) are passed as HTTP Headers of every request that is sent to Orthanc easing the integration with the orthanc-authorization plugin_
But Osimis 1.4.2 doesn’t pass an authorization url parameter as a header to Orthanc. Is there a way to add custom headers to Osimis requests?
