Has it been seven years? I'm going to assume that's a lie and move merrily on. ;)
As far as I know it's being used in several production sites, but I think there are a number of things that would be required of the library before I'd consider it of the quality required to pass a boost review.
Will read through the source code and see what time I may be able to commit.I've not had time to polish the library, add the full suite of tests it requires, add a client side part of the library*, etc. If yourself or anyone was interested in improving the library I'd be happy to accept pull requests (or bug reports)! A few others have helpfully already done as much.
The library is on github [1] in case you're looking for the current set of sources.
Cheers,
Darren* The library is kept relatively nice and simple by the fact it only addresses the use case of a website behind a general-purpose web server; maybe there is no need for a client-side part of it?
