CFHTTP CFCONTENT PDF

Data output tags. You can specify this tag's attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag's attribute names as structure keys. Now, ColdFusion attempts to get the content type from the file.

I've been playing around with ColdFusion Builder Extensions lately and I'm running into some very odd behavior.

Before I write anything about that, however, I wanted to confirm that a response driven by the CFContent tag and its Variable attribute is identical to a response driven by the standard ColdFusion output. As you can see above, starting with a single XML string, I configure the response in such a way that both responses halt immediately after the response data is written to the response output.

When we run the above code, we get the following page output:. Other than the "response-type" header value that I inserted to make sure that I didn't mess this up , there is zero difference between the two responses; both report the same status code, content type, content length, and actual file content - from the requesting standpoint, these two responses are identical.

I always thought you took the streamy approach because of some kind of performance gains or reduced server overhead you secretly knew about. Excited for the follow up. No performance gain that I know of. I just like the approach because it gives me ultimate control over what data is actually returned, including things like the content-length precision. Thanks for posting this. It made me realize that my headers were missing because by cfheader tag was placed after the cfcontent tag.

Basically, whether or not we want to use the CFContent tag to deliver the content back to the client as a binary stream. NOTE: this response is the Tick's war cry!! Standard Output Response Woot woot — you rock the party that rocks the body!

David, No performance gain that I know of. Barumpus Nov 11, at PM 1 Comments. Oh my chickens, this post is old! Hit me up on Twitter if you want to discuss it further.

Working the Webthe Power of CFHTTP and CFCONTENT

Since then, it has become a part of our everyday lives, whether we think about it or not. Usually, we make use of this protocol without giving it a second thought, like when we surf the Web. Sometimes, though, we have to actively use HTTP to solve problems. ColdFusion has built-in tags for HTTP support and, as Web developers, it is to our advantage to know how to use these tags efficiently. If we dumb it down to the lowest level, HTTP is a way for clients to request information from a Web server, and for Web servers to provide responses to those requests.

CFContent-Variable Response vs. Standard Output Response

I'm in the process of trying to write an interface to retrieve reports from an MS-SQL Reporting Services set-up in a variety of formats, PDF in particular , and have run into something odd This mechanism functions just fine if it's called directly from a browser. I've managed to cobble something together that takes the report-data and writes it out to a temporary file without any problems, though it's inelegant at best since there doesn't seem to be any way to specify a file-name just a path for CFHTTP to put Forum Rules.
