Just a thought . . .


If my understanding of cache is correct, a partial download of an swf file

would cause the browser to reload the entire file in order to begin viewing

it at another visit.  If you streamed only part of an swf file, the browser

would see that particular file in cache is not the correct size and does not

match the file being called and therefore recall it instead of use what is

in cache.


I think there are two things that say refresh me . . . the modified date and

the size.  If neither match, and correct me if Im wrong, it will perceive

the need to reload it again.


With all the way browsers deal differently with cache, I would not ever

count on caching accept to mess things up.  For example, I once posted work

prior to its completion and when the client went to see its progress, he was

not able to because the old file was trapped in cache.  Again, I called my

partner yesterday at home and asked him to try out one of our sites and he

said it worked.  I said clear your cache and he when he did, the site was no

longer accessible because the server was in actuality down.  Hence the need

for for meta tags that expire swf files rather than hoping the cache will

save your downloading time later.  Its really a shame that cache cannot be

more reliable.  Does anyone have a thought as to how to make it so?
