I have to get URL and parameters with SSI (only with SSI), but I can't find any solution.
For example: http://www.test.com/abc.html?data=something
And I have to get value of parameter "data".
<!-- set default value for SSI variable "data" -->
<!--#set var="data" value="" -->
<!-- get "data" value from URL -->
<!--#if expr="$QUERY_STRING = /data=([a-zA-Z0-9]+)/" -->
<!--#set var="data" value="$1" -->
<!--#endif -->
<!-- print the "data" value -->
<!--#echo var="data" -->
