Correct way to set a variable using regular expressions?
|
|
I am upgrading from Apache 2.2 to 2.4. In one of my pages I had the following;
<!--#if expr="$DOCUMENT_URI == /^\/([a-zA-Z0-9\-_]*)\..*$/" -->
<!--#set var="PAGEID" value="$1" -->
<!--#endif -->
This doesn't work in 2.4 unless I enable SSILegacyExprParser which I can do but I'd like to figure out how to upgrade the pages.
I've gotten as far as;
<If "%{DOCUMENT_URI} =~ /^\/([a-zA-Z0-9\-_]*)\..*$/">
<!--#set var="PAGEID" value="$1" -->
</If>
This is where I'm stuck. It appears that the back reference $1 is not stored as it was before but I can't figure out how to access the back references. Is this simply the wrong way to do this now? What is the right way?
