FW: Mysql over HTTP
am 07.04.2006 21:33:49 von JangitaYes this is very true Eric, thanks.
BUT there are LOADS of firewalls that don't allow non http traffic (like
mysql) over port 80; and your method wont work if all that's available is a
http proxy!
It is true that most firewalls open port 80 but as soon as they don't get a
valid http request they kill the connection hence the disguising of mysql
traffic as a normal (stateless I must add) http request
Some firewalls go as far as disconnecting anyone connected for more than 1
minute (assuming retrieving a page from a http server doesn't take more than
a minute)...

No need to re-invent that wheel:
Just use port=80 in my.cnf or start with --port=80
See http://dev.mysql.com/doc/refman/5.0/en/server-options.html
