Web Server : Apache 1.3.9

Issue :

The passthru call is not returning anything to the browser.  The call does not generate an error, but never redirects the output to the browser.

Reproduce :

   echo "<td><TEXTAREA name=log cols=60 rows=20>\n"; 
   passthru ("$FRUTILS\\cat $FRTMP\\$logfile");
   echo"</TEXTAREA></td>"; 

Where cat is a win32 executable that 'cats' a file and where $logfile is the file to view
