Re: [ACFUG Discuss] strange issue with cfcontent
Dusty, Have you contacted Host My Site about this issue? Do they have any throttling on long running requests that may interfere with what you are trying to achieve?

But they have to get through all the other checks before the cfcontent even runs. Is that what you meant validating? Hopefully this is secure enough for the balance of security decisions. On another note. Dean you are a cool guy. Even though I once left a negative comment about one of your threads, you continue to respond to my issues with good useful advice. I have thought long and hard about that comment I left inspired by your disagreements with Robert (I think that was his name) and I say here and now, I was wrong to leave that comment and officially retract it.

re[2]: [ACFUG Discuss] strange issue with cfcontent
I know I'm a bit late to this, but I was thinking this direction as well: copy the file to a downloadable version with a guid in the name in an accessible directory, so others can't guess it and then use OnSessionEnd to clean it up. Added benefit is that CF is out of the picture and the webserver will take care of transferring the file... /m : Also could it be that cfcontent is not such a good approach for doing what I : described. Basically keeping the files out of the webroot for security. Is : there another better approach. Maybe create a process that temporarily : creates a folder and copy of the file for a normal direct link to download : and then wipe it off after a time. That was just a quick thought. : Dusty - Annual Sponsor FigLeaf Software - http://www.figleaf.com To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -
Re: [ACFUG Discuss] strange issue with cfcontent
speaking of throttling, there is a * Request Throttle Threshold *in CF these days as well as * Request Throttle Memory *.

Hey Doug, though it's rather pitifully documented, all I've seen indicates that these throttles (new as of 7) are for file uploads, rather than CFContent.

Re: [ACFUG Discuss] strange issue with cfcontent
Well, of course, that requires Enterprise, and even many hosting companies still try to get away with using only Standard, even in shared hosting packages. Shame, really (for the lost benefit of sandboxing as well). /charlie Steven Ross wrote: It is strange that a shared host doesnt have seperate CF instances going to protect you from this kind of thing.

Re: [ACFUG Discuss] strange issue with cfcontent
Right, I agree entirely. If they are about uploads only and not requests in general (as I've heard), then they should be renamed or at least expanded upon, for sure. /charlie Douglas Knudsen wrote: Now I've heard the response before that all three settings pertain to uploads, but the below contradicts that. A 'request' in CF terms is not limited to uploads. How this works and where is this queue as it relates to thread counts and such is well, unknown to the public. If they truly are specific to uploads only, then they ought to be renamed, eh? looking at CF8 docs http://livedocs.adobe.com/coldfusion/8/htmldocs/basiconfig_05.html#1215023 and CF7 docs...well I can't bloody find it on livedocs. we have from the cf8 live docs: Maximum Size Of Post Data Limits the amount of data that can be posted to the server in a single request. ColdFusion rejects single requests larger than the specified limit. RequeSt Throttle Threshold Requests smaller than the specified limit are neither queued nor counted as part of the total memory. Requests larger than the specified limit are counted as part of total memory and are queued if the request throttle-memory size is exceeded. Request Throttle Memory Limits total memory size for the throttle. If sufficient total memory is not available, ColdFusion queues requests until enough memory is free.
