When saving a PDF, how to avoid a re-dl'd - when it is in *already* in the cache

G'day Folks,

I refer to a PDF - but this applies to anything which has already been received and is thus in the local cache...

When I choose to save a PDF, FF re-downloads the file.

Why? ... that just wastes bandwidth. NB: I am on dialup and such activity can be *very* annoying & unnecesary. Especially when the PDF (or whatever) is quite large.

Of course, some will argue that the (PDF) file may have been updated in the meantime - and the (very) latest version should thus be downloaded.

However, I believe that is (a) highly unlikely and (b) should, in any case, be a user choice.

I have searched for a switch/option to modify this crazy behaviour - but can't find one. Have I missed it ..? If so, *please* tell me where.

If this crazy behaviour cannot be changed, is there an app which will allow the user to examine the cache and save the PDF... ie: independently of FF's "save as"?

Many Thanks Barry

I can partially answer my own question .. ie: workarounds.

But if anyone knows how to handle this without workarounds, I'd appreciate a post please.


Alternatives/workarounds:

1. Type "about:cache" into the FF url box - and it will show a list of cached items.

 It is then necessary to search for what you require 
 - which may not always be so obvious.   
The location on your (local) HD should then be available/visible.
   

2. Use a (free) standalone program, eg: MozillaCacheView - Nir Sofer

 <http://www.nirsoft.net/utils/mozilla_cache_viewer.html>

Option 2 may be the easiest - but is not ... 'integrated', so the usual caveats apply.
