Convert single .js into a ie and non-ie .js

I also considered that option but decided to go for the singe-file solution as stripping the VML part only saves about 380 bytes after gzipping. And since it adds an extra request for the browsers which are already the slowest ones, I thought having a single file would offer the best trade-off.

I was thinking more of having two files: ie.js and non-ie.js

Using ie conditional comment fun we guarantee that only one of the two requests is made. Ie will request ie.js and everyone else non-ie.js. This way 1 request, bytes saved, everyone is happy. Potentially some code could be avoided as well because we are guaranteed to be in IE vs not.

Whopse closed issue.

Just a thought experiment: how many extra bytes are needed for the conditional comment code? =D

[teddyzetterlund]

Not worth it. The conditionals themselves would add at least 110+ bytes (so we'd save maybe ~270 bytes) and four extra lines of ugly code compared to one clean script tag. My opinion is that it's enough that modern browsers skips the parsing of the IE specific bit.

Good point...
