Question

I’m supporting a legacy application on ColdFusion 7, and the pages are full of painful amounts of whitespace that I’d like to gzip away.

I know I can:

• manually compress everything in an index type file (reference)
• enable it in the web.xml (which I don’t have access to)

But can I just throw the right < cfheader > or something akin to a .htaccess that triggers gzipping on this directory?

There are two ways to implement compression. At the web server level (apache 1.3 with mod_gzip or mod_deflate, IIS_6, IIS_7) or the application server level (coldfusion via a servlet filter).

I’m afraid those are the only options available to you for compression.

Otherwise you’ll be looking at one or more of these:

• enabling whitespace suppression via
  cf administrator.
• using <cfsetting
  enablecfoutputonly=”true”/> where
  possible.
• wrapping code with
  <cfprocessingdirective
  suppressWhiteSpace=”yes”></cfprocessingdirective>
• wrapping code with <cfsilent></cfsilent>
