1721580 - View-source on a POST result page silently resends POST data if page no longer in cache

Status: NEW

(Toolkit :: View Source, defect, P3)

Description

[:Gijs (he/him)]

+++ This bug was initially created as a clone of Bug #479296 +++

(see bug 479296 comment 14 where Boris notes that view source does this.)

STEPS TO REPRODUCE:

1. Load a POST result page
2. Clear the cache.
3. Tools > Browser Tools > Page source (or accel-U)
4. Either make an HTTP log as you do this, or have access to the server, or use
   a server that produces different output on every POST.

EXPECTED RESULTS: No silent repost

ACTUAL RESULTS: silent repost

For history traversal, we make sure to never do this. If the POST page is not cached, we put up a dialog asking the user whether to resend the POST data.

Is that the behavior we want here? Do we want something else (like showing the source of the live DOM, or offering the user a choice between those options)?

I can easily reproduce on my machine.

It's possible to see the POST request in the BrowserToolbox. Just have it opened with the Network panel selected at the time when the page source is opened.
