How to deal with the C10K problem with a simple script?
patio11: You're overthinking this.The client doesn't mean that 10k people are going to hit the site at the same microsecond.  The client means that there will be 10,000 eventgoers accessing the site within a particular period.  Many of the clients in this industry, being cough fundamentally non-technical people, believe that the period of reference is "one day".As you've probably noticed, a $20 a month VPS plus Apache can easily chew through 10k visitors in a day (I wouldn't use Apache personally, but if I were competent at configuring it, yeah, no problem whatsoever).  Adjust upwards if your client anticipates a particular instantaneous deluge (think "Steve Jobs stands up at the keynote and says 'My robot minions, all of you need to hit this URL right now!').P.S. Your client is wildly overestimating the audience that will actually come to the site.  Don't tell him I said that.
