[Feature] Refresh after form submit

[Jixabon]

Is your feature request related to a problem?

Currently after submitting a form or saving configurations, when refreshing the same page (which contains multiple tabs) the browser will ask if you want to resubmit the form. This can cause potential resaving of fields with potentially unwanted or unexpected values. This also makes it difficult to simply get the latest data on the page.

Describe the solution you'd like

Some potential solutions:

• Follow Post/Redirect/Get pattern. Once finished processing data from the POST set header to current location which will make it like a normal page load. This could be a relatively straightforward implementation but could potentially cause issues if there is code that's run after the render function that uses POST data.
• Move to more ajax calls. Avoids this issue all together but would require a bit more work to implement.

Additional context

This would likely require some fundamental changes to a handful of pages so I'm open to a discussion on the vision for how the pages should work going forward.

Some of the forms tend to have a lot of messages on save. To try and reduce these visually I got the idea of a more ajax type flow. Form is submitted and a modal that is populated via JavaScript shows that can show progress messages. The ajax endpoint would keep an open stream sending update messages as things are saved or set. Nothing like websockets, but just a "long loading" page. Once the ajax is completed with a successful message reload the page to then show current state and with a single general success or fail message as they normally are shown.

In the case we want to preserve the "message log" some sort of drop-down to show the log within the alert could be a good solution.

Some forms have a lot of messages on save (looking at you, hostapd). The live form submission trades this for useful updates inside a modal dialog.
