I'm wondering what sort of machine I should get to be a reverse proxy. I've never made one before so I'm sort of confused as to what kind of spec I should look for. So I guess my question is.. how expensive would it be for a machine to forward say.. 50,000 connections a day? What sort of machine should I look for?
50000 connections per day is less than a connection per second in fact. This kind of load is not too high, any average and even below average PC can handle this amount of traffic.
To compare, one of my sites serves about 4,000,000 hits per day using a HP DL360G5 and the reverse proxy shares this hardware with Apache/mod_perl, MySQL and some other stuff.
