<DIV><FONT size=2>You access memcached via keys. Each key has a id and value. If
you were to select a row from a database you would put the result of the query
into memcached via a key. Here is an example of how that would work in
perl:(from danga's site)</FONT></DIV>

<DIV><FONT size=2>1. You need to destroy the cache via a delete and then
rebuild it with the new data. Your application is responsible for keeping
the cache up to date.</FONT></DIV>

<DIV><FONT size=2>2. Drop apache and use Lighttpd. It will use less memory
and therefore leave you with more memory to use with memcached.</FONT></DIV>

Newbie inquiry</DIV>
<DIV><BR></DIV>Hi ALL,<BR><BR> Im trying to get enough details
on memcached to check whether it is feasible to use it on a site that is
very dynamic.<BR> Can anyone clear my clouded mind.
:)<BR> 1. If data are cached and in the event that the
page was updated what happens to the cache? will it be completely
reconstructed? or only portion of it will be replaced?<BR>
2. Would you recommend memcache to sit on the same box with apache
with a 4G RAM
resource?<BR><BR>thanks,<BR></BLOCKQUOTE></SPAN></DIV></BLOCKQUOTE></DIV><BR></BLOCKQUOTE></BODY></HTML>
