Firstly - Sorry for sending an OT item to this list. I kinda feel we have a
good group of experts here, so I'm hoping someone will have some guidance.
The issue:
When users try to download files they work nearly all the time, though today
it seems files that are above 30MB (rough estimate) fail when downloaded. CF
sends the most basic error message: "An error has occurred." That's it, no
line number, nothing.
We've narrowed it to what we think is the issue but I'm still skeptical if
it's really the problem, though most likely. This being the size of the
file, due to using CFFILE action="read".
Now, I'm guessing reading a big file into CF to then send out to the browser
is a bad thing, due to the load on the memory. Does any one have any
guidance on a better way to send the file to the browser?
Here is the code I use to send the file to the browser, the variable results
are below. The goal is to prevent the user from having access to the path.
They just get sent the file.
<cffile action="read"
file="#PrimaryDrive##GetFolderPath.FOLDER_PATH##GetFileDetails.FILE_NAME#"
variable="FileContent">
<cfheader NAME="Content-disposition"
VALUE="inline;filename=#GetFileDetails.FILE_NAME#">
<cfcontent type="#GetFileDetails.FILE_MIME#">
<cfoutput>#FileContent#</cfoutput>
CFFILE PATH: D:\ProjectFiles\52070G\CYLINDERBLOCK\cylblockcast130306.zip
CFHEADER VALUE: inline;filename=cylblockcast130306.zip
CFCONTENT TYPE: application/x-zip-compressed
As I said works almost all the time, except on large files. At least that's
the pattern so far.
Thanks for an help you might be able to offer,
