14781 - View Source refetches the document!

Status: VERIFIED DUPLICATE of bug 6119

(SeaMonkey :: UI Design, defect, P3)

Description

[Hixie (not reading bugmail)]

When you choose View Source, Mozilla goes and refetches the document on the net!

This means that you cannot view the source of dynamically created documents.

TO REPRODUCE:
  1. Go to http://www.bath.ac.uk/%7Epy8ieh/cgi/formtester.pl
  2. Click on the check box in the "Simple POST Form".
  3. Submit the POST form.
  4. Notice it says "Results of Last Submission" at the top of the page.
  5. Choose View Source (in Viewer, File|ViewSource).
  6. Look for the text "Results of Last Submission".

ACTUAL RESULTS:
  The source shown in ViewSource is NOT that used to render the document.
  This can be clearly seen by the fact that the markup in ViewSource could
  not generate the document seen! The entire "Results" section at the top of
  the document is missing, because Mozilla went and refetched the page.

EXPECTED RESULTS:
  Mozilla just uses its (in-memory) cached copy of the document for the
  ViewSource window. No network connection should be made for ViewSource.

NOTES:
  IE does this fine. Also note that making sure that the document is refetched
  using exactly the same call IS NOT a suitable fix, since:
   a. If the document is the result of a POST submission, refetching it could
      trigger things like a bank transfer!
   b. In any case, dynamically created documents may be different on each fetch
      regardless of whether it is a GET or a POST -- think random quote pages.
   c. If the page takes a long time to load (e.g., it is created by a slow
      script) then you don't want to wait the time again!
  We must use a local copy of the page for View Source!

Warren -- I'm giving this to you as a placeholder. When the cache is in, this
bug will go away by itself.

Yup, it's a dup.
