The downside is that you reset cache too often, but it's not overly significant unless the target file for the revision is changing a lot. In my actual usage, I'm using the revision of my 'static' directory for all the stuff within in. So when I change any static asset, all of them get a new number. But I don't change static assets very often, far less often than I change CFML files, so I still get a significant caching improvement. I could do it per file, but the benefits weren't worth the complexity, so I skipped it. Brian,

That still seems to have the same problems though - if you're using this to set revision numbers for caching on JS and CSS, you're setting it based on an unrelated file? I guess the drawbacks are offset by the use case - personal sites where you don't sweat the deployment details so much. I run all of my wordpress sites via SVN similar to what you described above... svn switch to the next tag.

If you check jquery.js, then no, it won't change until you actually update jquery.js. At a lower level, this is returning the last revision for the given file/directory, not the HEAD revision of the working copy. Where I don't deploy a svn working directory (i.e. use an Ant/Rsync deploy mechanism), I do pretty much the same thing. Write out a VersionInfo.cfc file that has all kinds of info about the release (name, revision, date, builder, etc.) Brian,

The revision of your application will always be the most recent commit version so even if you haven't changed jquery.js in 2 years, if you change test.cfm you're going to have a new m=XXX value, no?
