Coldfusion download file from server

ColdFusion Summit Survey. Adobe Developer Connection. ColdFusion Community Portal. Online ColdFusion Meetup. Windows Support. December 13, ColdFusion installer refreshed. PiyushN Follow. Newbie 25 posts. Followers: 1 people. For a detailed description of these new features follow the links embedded in this technote.

The API Manager installer would be made available very soon. We will update this post to share the location where the installer would be hosted. For details on the changes that went out with Update 3 refer the Update 3 Release Notes document. The build number for this installation should be ,00,03, The features listed below have been retired from the product and no longer ship with ColdFusion. For a detailed overview of the affected areas, refer the "Portlets" and "YUI and Spry" sections of the coldfusion-deprecated-features technote.

In case you need to use any of these libraries you can download them from locations mentioned below. To integrate the downloaded library, follow the instructions below: Stop ColdFusion sever. In UNIX, you can individually set permissions on files and directories for each of three types of users' owner, group, and other. You use a number for each user type. This number is the sum of the numbers for the individual permissions allowed. Values for the mode attribute correspond to octal values for the UNIX chmod command:.

You enter permissions values in the mode attribute for each type of user: owner, group, and other in that order. For example, use the following code to assign read permissions for everyone:. After a file upload is completed, you can retrieve status information using file upload status variables. This status information includes data about the file, such as its name and the directory where it was saved.

You can access file upload status variables using dot notation, using either file. Although you can use either the File or cffile prefix for file upload status variables, cffile is preferred; for example, cffile. The File prefix is retained for backward compatibility. Note: File status variables are read only. They are set to the results of the most recent cffile operation. If two cffile tags execute, the results of the first are overwritten by the subsequent cffile operation.

The following table describes the file upload status variables that are available after an upload:. Initial name that ColdFusion uses when attempting to save a file; for example, myfile. Full name of the source file on the client system with the filename extension; for example, myfile. Size of the file that was overwritten in the file upload operation.

Empty if no file was overwritten. With the cffile tag, you can create application pages to manage files on your web server. You can use the tag to move files from one directory to another, rename files, copy a file, or delete a file. The examples in the following table show static values for many of the attributes. However, the value of all or part of any attribute in a cffile tag can be a dynamic parameter. Note: Ensure that you include the trailing slash when you specify the destination directory.

Otherwise, ColdFusion treats the last element in the path as a filename. This rule only applies to copy actions. In addition to managing files on the server, you can use the cffile tag to read, create, and modify text files. As a result, you can do the following things:. We found that it wasn't even with large files, but lots of small files being called as a result of the "same" request would give the CF server problems terminal ones.

So we stopped doing that I haven't investigated this since CFMX6. Just to ask this again, what is the alternative way to use Coldfusion to securely serve large or a lot of files? I think there could be multiple ways. One potential way would be to use a temporary directory thaqt you can link to. Perhaps a directly named like a UUID. The issue there is that you don't want N copies of very large files. In Linux, I'm assuming you could make a I forgot the name.

Oh, link. I'm not Linux expertt at all, but I believe that would work, and not fill up your hard drive. In Windows I'm not sure what would work best.

Any ideas folks? I do this This also requires additional garbage cleanup of the temp files. The next thing I'm looking into is archiving all of the requested files into a single ZIP file and then passing a hash to a Flash 8 applet that will allow download of the files. Once completed, Flash will send a background request to the server so that the server can perform the needed cleanup. Ray, I've found that the code you provided does not properly work when the file contains spaces; the download prompt will chop part of the file name.

A small modification will make it work. I'll echo the majority here, this type of solution works great for small files or low capacity! We are having the same problem securely serving large files with cfoutput.
