when use coldfusion 10, locally, can read zip file's text file content using:

<cfzip action="read" file="http://someurl.com/somezip.zip" entrypath="sometext.txt" variable="somevar"  /> 

but on railo vps, produces internal server error 500 on iis7.5

not sure railo, according <cfzip> doc, acf not support reading off http://, ram://. should use <cfhttp> download content first.
