I would look at Amazon AWS CloudFront or similar services from RackSpaceCloud or VPS.net. Hosting what you hope to become popular videos on one server is almost guaranteed to fail or run up serious bandwidth charges or both. On Wed, Jan 5, 2011 at 11:38 AM, JTSM wrote: > ... my thought is the m

Hi Hernán, I'm curious... I'm neither a memcache expert nor a C programmer, but having read your proposal, can you not store the keys of the related items in another set? Is that how you're doing it now and want to avoid two round trips to get & deserialize? Just trying to understand your use case

Sorry, I see you provided error output. Connection refused, eh? Are you connecting to localhost or another server running memcached? Try opening port 11211 with iptables (if CentOS - did you say what distro you are using?)

Re: reading data from php client

It's unclear from your code sample how you are instantiating the memcache class instance. Meaning, $memcache isn't set? Try this: $memcache = new Memcache; $memcache->connect('127.0.0.1', 11212); $memcache->set('sample3',2); $foo = $memcache->get('sample3'); print_r( $foo ); On Sun, Jun 5, 201

Check the memcache_set PHP docs - give it a NULL flag and specify your $timeout (as a unix timestamp in the future) explicitly - or pass a timeout of 0 for (never expire). It may be that its expiring the moment its set. On Tue, Aug 23, 2011 at 12:29 AM, 1989moni1989 wrote: > Hello! > > I have a

Re: I need help setting up memcached

Aaron, It's not something you just upload to your web files. Memcached (the daemon) has to be built from source and run from the command line like so sudo /usr/bin/memcached -u nobody -m 64 -l 127.0.0.1 -p 11211 You then have to compile and install the extension for PHP. Read more here: http:/
