Is there a way to preserve preferences in a custom connector to save the DataSource URL?

[ECorona]

I'm making a custom connector, my final user usually uses the same Server everytime he uses the connector, but he need to type the URL everytime, the thing is, the URLs are really hard to remember for a human. So, I'm wondering if there's a way to save "preferences", my idea is if the user can sign-in sucessfully then save the URL somewhere, so, the next time the user uses the connector does not need to type (or copy-paste in my case) the URL.

I cannot save the the URL as hardcoded string in my source code, because, the connector is distributed to my final users and each of them has their own URL where they extract the data.

HI @ECorona,

Current custom connector does not support these, you can't use it to cache data or stay connection string data as default value.
For your requirement, I'd like to suggest you create a global credentials to cache to the locate. Then you can choose it to use as credentials in your data connector.
