Hello All,

Trying again with this one.
Is anyone able to repeat it using the example below and if yes ... is there a way to \
achieve what I was trying to do (without launching an external program)?

Hello,

I had expected the expression below to print out "File index.htm exists" given that \
it does exist in same location as the page that loads this ... but instead it tells \
me that it does not exist.

<!--#set var="filename" value="index.htm" -->
<!--#if expr='-F "%{filename}"' -->
	File <!--#echo var="filename" --> exists
<!--#else -->
	File <!--#echo var="filename" --> does not exist
<!--#endif -->

If I replace 
<!--#if expr='-F "${filename}"' -->
with
<!--#if expr='-F "index.htm"' -->
then it does find it.

I tried with %{filename} as well.

So - it appears that variables not expanded in this case or I am doing something \
wrong. Any hints?

My real-world usage is more complicated because the var filename really is \
dynamically generated based on current date/time.
