#Archive program free that does stream archives zip file

To experiment with creating and streaming a ZIP file in Lucee CFML, I'm going to As such, I've looked at using the STORE method with the zip CLI in Lucee CFML to archive images without as much CPU overhead. As such, it doesn't make so much sense to store them in a ZIP file using the DEFLATE method since it's just a waste of CPU cycles. And, I'm going to download and ZIP them together on-the-fly:ĪSIDE: As I've discussed before on this blog, image files are already compressed.

To experiment with this idea, I grabbed a few of the latest image URLs from my People page. Then, as we add Zip entries into the ZipOutputStream, the ZipOutputStream will handle the compression and write the deflated-bytes to the CFML output for us. And, that's exactly what we're going to do in this experiment: we're going to create an instance of Java's object and have it write directly to the ColdFusion response output stream. Or, we can have another 'writer' pipe data into the response on our behalf. With this response output stream, we can start writing any kind of data to the output. And, by using the Page Context object, we can get access to the underlying Response Output Stream to which ColdFusion writes our String-based CFML content. But, I have a rough-enough understanding of how Input and Output Streams work. Now, I will heavily caveat that I know nothing about Java servlets. However, under the hood of every ColdFusion response is a Java Servlet Page Context, which we can access with the function, getPageContext(). This is often in the form of CFML / HTML for a page response or, something like JSON (JavaScript Object Notation) for an API response. Typically, when generating a ColdFusion response, we are dealing with Text data.
