Question
I was reading about SSI here. The first code example under the section Control Directives looks like this:
<!--#if expr="${Sec_Nav}" -->
<!--#include virtual="" -->
<!--#endif -->
What does the "$" sign mean? EOF, a function, get...???
Thanks!
Solution
It is just a way to inject a variable value inside a string
<!--#if expr="${Sec_Nav}" -->
this is comparing expr to the value of Sec_Nav
