If you make multiple requests to a Web Service you can improve performance by not making ColdFusion set up and prepare the connection repeatedly. How? Instead of using use CreateObject(), this way ColdFusion maintains Web Service information in a variable that can be used repeatedly. And you can...
If you need to share session data across a cluster then you must use CLIENT variables. Right? Wrong! CLIENT variables can indeed be shared, but if you are using ColdFusion for J2EE (and J2EE managed SESSION variables) then SESSION variables can be clustered too. There is one gotcha however,...
ColdFusion MX for J2EE does not have a checkbox for enabling white space suppression. This is an oversight, the option is actually supported, it is just not exposed in the Administrator. The solution? Edit the configuration file directly. Here's what you need to do: 1) Stop ColdFusion. 2) Open the...
Web Services are invoked using . Right? Not necessarily. ColdFusion MX will actually allow you to invoke Web Services using CreateObject() using the syntax CreateObject("webservice", "wsdl") (replacing "wsdl" with the wsdl URL). CreateObject() returns and object allowing you to invoke methods using...
If you are using / the order of the blocks does not matter - ColdFusion will find the best fit. This is unlike earlier versions of ColdFusion where "any" had to be the last block (or it would catch all errors). (Applies to: ColdFusion MX)
If you are using then you should never have code that is in the block but not in a or . ColdFusion 5 allowed this (mistakenly) and ColdFusion MX no longer permits this (although you should never have been doing it anyway). (Applies to: ColdFusion MX)
The has been deprecated as ColdFusion MX now has far better (and more open) ways of interacting with Java code. (Applies to: ColdFusion MX)
can be used to access secure pages (using https instead of http) by simply prefixing the URL with "https". By default port 443 will be used (alternate ports may be specified if needed). (Applies to: ColdFusion 4 and later)
is used to manage Verity collections. When using this tag (except perhaps to list available collections) use to protect the collection from other access. (Applies to: ColdFusion MX)
Need a list of available Verity collections? Use the tag and set ACTION="list" to obtain a query containing collections details. (Applies to: ColdFusion MX)
