Server Connect With URL Params In Content Page Load

I have a content page that has a server connect on it, it takes url params lets say A and B something like now I have an issue with how the server connect loads for example if I have it set to auto run it will run twice once before the params are noticed and once after meaning the first call is always an error (also runs again on leaving page causing another bad call).

Before the new app connect updates I could solve this issue using a page flow on auto run to initiate the server connect without an auto load but now this will only run the server connect once as expected but its doing it without params so its always a bad call until I refresh the page.

Is there a better way to do this in short im wanting a server connect on a content page to only run once on page load with the url params noticed and to not load again when the params are changed to navigate to another page like
