The way I understand it (someone correct me if this is wrong), when you've got a certain shared resource that, for one reason or another, can only be accessed by one process at a time, you'd use a semaphore.

Basically, the semaphore is a variable that keeps track of all the processes that currently want to access the shared resource and it makes sure only one process at a time actually accesses it.

NAME
WebCommon::urlEncode - URL encode a string SYNOPSIS
String urlEncode( String x ) ARGUMENTS
x The string to encode DESCRIPTION
URL encode a string. You should use this to encode reserved characters in URLs that you wish to be passed literally. // trying to pass "http://www.example.com" as a parameter url = "http://localhost/test.cgi?url="; url += urlEncode("http://www.example.com"); // url = http://localhost/test.cgi?url=http%3A%2F%2Fwww.example.com Note that in the example above, encoding the whole URL would be incorrect - that would create a relative URL beginning "http://".
