FireFox, IE, and TCC all get the page from the same Akamai/RoadRunner cacheing server.

Why are the results different?
Bet you half a dollar the cache is load-balanced, and you're getting different servers with different programs. Maybe it's checking the user agent so that the results are consistent?

When I visit

http://weather.noaa.gov/weather/current/KSYR.html

with FireFox or IE (right now) I see the current weather conditions in Syracuse as of "Nov 11, 2010 - 11:54 PM EST".

When I TYPE that URL, I get the conditions for "Nov 11, 2010 - 04:54 PM EST".

You've completely lost me. Why would you think that TYPE would execute HTML code?

(TCC is definitely *not* caching anything, though who knows what Windows might be doing ...)

I presume "When I TYPE ..." refers to using the TYPE command in TCC to access the URL. I repeated your test, using one of the locations in my vicinity (Ft. Meade/Tipton, MD). I saved the output of the TYPE command into a file, which I displayed in a Firefox tab, together with the Firefox direct result; they were identical. You may try another test - concurrently download the webpage from multiple different TCC processes, and see if they are identical. BTW, my cable ISP is Comcast.
I am wondering if your observation has any relationship to my repeated observation that using TCC's FTP access to the JPsoft website often locates cached older files when newer ones have already been put on the server.

I too do not understand exactly what You mean.
I tried typing, in TCC/LE 12 build 35, these two commands:
1) type http://weather.noaa.gov/weather/current/KSYR.html
2) http://weather.noaa.gov/weather/current/KSYR.html
The first gave me an error:
TCC: (Sys) The filename, directory name, or volume label syntax is incorrect.
"http://weather.noaa.gov/weather/current/KSYR.html"
The second shows me an internet page in internet explorer (my default browser).
Using firefox, opera, safari or chrome I get the same result.
So, apart from time zones I cannot guess why You should see any differences.

You can use TYPE on a URL. It simply shows the source:

Code:
v:\> type [URL='http://weather.noaa.gov/weather/current/KSYR.html']http://weather.noaa.gov/weather/current/KSYR.html[/URL] | notags |
