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)? Paul Webster On Mon, 04 Mar 2019 17:27:53 +0000, I wrote: 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.
