Internal Links and distribution of PR

One of my homepages has a PR of 4 (www.msmaustralia.com.au) and most pages
down from that had a PR of 2 or 3.
I have just re-structured my site to use PHP. This has meant changing most
of my html pages to php pages.

Before the change to using PHP, All my internal links from my homepage
specified the entire URL, including the extention (ie
http://www.msmaustralia.com.au/products.html)
Now that I'm using PHP, most of my pages have changed to have an extention
of .php (ie http://www.msmaustralia.com.au/products.php), and my PR has gone
to 0 on those pages. OK, That I can understand. Technically they are no
longer the same pages (the full refering URL is different).

What I want to know is this.
I have now specify my internal links from my homepage without the extention
(ie http://www.msmaustralia.com.au/products), when the PR is restored (next
PR update I presume) will this result in PR being effectivly allocated to
any extention if the requested (or refering) URL does not specify an
extention? (ie http://www.msmaustralia.com.au/products).

Or, to put it another way, can PR be allocated to a URL without an
extention? (ie http://www.msmaustralia.com.au/products).

Thanks... Philip Middleton.

As I understand it, PR can only be allocated to specific pages. If you
have links such as http://www.msmaustralia.com.au/products then any PR
value to be distributed from the linking page will go to whichever page
is displayed by that URL. This will normally be something like
index.html, default.php etc.

Presumably you have set something up to define what file is used in
such cases (index.html is the default, but this can be changed to
whatever you like).

http://www.yoursite.com/products is a different URL than
http://www.yoursite.com/products.html and
http://www.yoursite.com/products.php is yet another one. Therefore you
cannot expect the PR to sort of "automatically" get restored to exactly
the same level it was before. In Google's "mind" (if one can use this
word) it's a different page, and it has to be evaluated for PR separately.
It may not even get to the same level because some of the links that are
pointing onto your site from outside will not be updated for a while (if
ever), so you are going to loose some incoming link weight in terms of
calculating the PR.

Thankyou for your Answer.
I understand what you are saying.
My question is more to do with how my page is referenced.
OK, I understand that http://www.msmaustralia.com/products.html and
http://www.msmaustralia.com/products.php are differnet pages (according to
google bots).
I also understand that doing something like
link:http://www.yoursite.com/products.php and
link:http://www.yoursite.com/products produce different results.

So, my real question is...
As there are no external links (that I know of) to this page, the PR has
come exclusively from the home page.
If I only internaly link to http://www.msmaustralia.com/products not
http://www.msmaustralia.com/products.php, my understanding (be it a little
limited) is this. Google will assign PR to
http://www.msmaustralia.com/products.
When my homepage is spidered, the spider comes accross the link
http://www.msmaustralia.com/products and the server is expected to find the
apprepriate page (html, php, asp shtml or whatever), so, google will simply
assign PR from my homepage to http://www.msmaustralia.com/products, and so
"effectivly" you have make http://www.msmaustralia.com/products.* all have
the same PR.
(linitations: Can only actually have 1 page, and have to always refer to it
as http://www.msmaustralia.com/products and never the full URL, and cant
have a directory and a file with the same name)

I know that for a single static site, this is a bit pointless, but I'm
thinking more along the lines of when building sites, you could then change
the format (ie from HTML or PHP or ASP or whatever) without suffering the PR
loss like I have just done.

Does this logic seem sound to anyone?

Or, does googles bot somehow find out the extention of the file and assign
PR to the full URL regardless? (I cant imagine so).

OK. Some background on what brought this up.
My homepage for this site had PR4, and most of the pages has PR3, or PR2
I have always got external links to link to http://www.msmaustralia.com (so
the server was expected to serve up the index.html file).
When I changed over to PHP, I changed my index page to PHP, as well as most
of my other pages.
My home page (index page) still has PR4, but my other pages dropped to PR0.
This got me thinking the the PR is assigned to how the page is linked to.
(?correct?)
So, I got to thinking that in future, I might not include the extentions to
any files so that if/when I ever do that again, I dont drop PR.

Maybe that explains why I'm asking such a strange question.

Comments?

Thanks... Philip Middleton.
