Imagine you have a page example.com/remove_me.html (call it A) that is

to get rid of page A in Google cache, but this url still generates traffic so you redirect it to B with 301.

When you enter (in the remove tool) url for A Google checks its existence. It is redirected to page B with 301. Then Google fetchespage B that it was redirected to. This page B exists - so now Googlesee 200 - and it refuses to remove page A, as it assumes it stillexists. The only sure cases when Google doesn't refuse to remove Ais when it is either blocked by robots.txt (then it doesn't matterif the page exists) or when GET A returns 404 (probably other codes- like "gone" - too).

Borek, perhaps you were using a 302 redirect. I removed hundreds of pages from the index this summer that had been gone from the serverfor more than a year now (if only there were some way to remove thesame pages from Yahoo!'s index) but my server was sending 301 redirectsfor the missing files from various domains. 

No contradiction here, but I decided to check details.

Take a look at this URL:

http://www.chembuddy.com/ ?left=BATE&right=overview

It 301 redirects you to

http://www.chembuddy.com/?left=BATE&right=basic_acid_titration_equilibria

Both pages are indexed by Google (although the first has no cached
version).

Try to remove the "overview" link - Google shows message "That page
appears to still be on the web".

So redirect 301 to new page that gives 200 is considered "page still
exists".

Best,
Borek
