I am storing a grunch of files of different types in a directory on my
server. For obscurity (don't ask it's a legal thing) I store them with names
like DOC_**.AAF Where the ** is an id number. I store the mime type and
orignal filename in a database table. My Flash application calls a
coldfusion template called download.cfm with a URL variable with the
document id number. The template looks up the data in the data base and
sends a page back with CFHEADER and CFCONTENT set to download the
appropriate file with the correct filename. This works in both Netscape and
IE when called from Flash using getURL and a javascript call to pop up an
undecorated window.
If I call the same page using an anchor from an HTML page it doesn't work.
IE tries to name the file "download.cfm?document_id=**" and can't find the
file to download. It is as if the CFCONTENT and CFHEADER were being ignored.
I have check to verify that they are getting good values.
Here is the code from download.cfm:
<cfif metadata.recordCount GT 0>
<cfset
localfilename="#GetDirectoryFromPath(GetBaseTemplatePath())#storage\DOC_#URL
.document_id#.aaf">
<cfheader name="content-disposition"
value="attachment;filename=#metadata.file_name#">
<cfcontent
type="#metadata.contenttype#/#metadata.contentsubtype#"
file="#localfilename#">
</cfif>
Can anybody explain why this technique works fine when called using
Actionscript
getURL("http://"+server+"/Users/download.cfm?document_id=" +
documentObj.document_id);
But this HTML won't:
<a href="http://www.mydomain.com/Users/download.cfm?document_id=**" >The
Real Filename.ext</a>
