RE: cffile upload large files again!
Sorry about that. I guess I should have paid more attention to your original post. :) -Original Message- From: George Abraham [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 07, 2005 3:27 PM To: CF-Talk Subject: Re: cffile upload large files again! Robert, That one specifically talks about reading in text files already residing on the server. I bet that could easily be modified for reading in uploaded files. Thanks for the link.

George, Take a look at this technique by John Bartlett. http://johnwbartlett.com/cf_tipsntricks/index.cfm?TopicID=96 Robert -Original Message- From: George Abraham [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 07, 2005 1:32 PM To: CF-Talk Subject: Re: cffile upload large files again! Thanks Dave, I don't see any UDFs on cflib that deal with what you talk about, though? I searched using various terms, but nothing turned up. I do understand what you say about streaming the file while uploading. Can this be done using the java.io.InputStream class?

I do believe you'd need to using the InputStream class to get this done, though I'm not a strong enough Java developer to really help you out there. Hopefully somebody else can chime in more definitively?

Remember, the cffile tag reads the *entire* file into memory (if it can) and only then does the "action" request. I'll bet money that your "crap out" was an OutOfMemory error at the Java level -- you were just looking at the wrong log file, which is why you didn't see it. If you're serious about allowing uploads of the sizes you're talking about, then streaming the file will be much more efficient. There are some UDFs at cflib.org to help you out with this. Also, if you're using MX 7, there is a new memory throttle on the "Settings" page called "Maximum size of post data" to help prevent against DoS attacks. Make sure that you up the default 10MB setting to the size of the largest file you anticipate to accept, or you'll hit that road block as well.
