Cannot say I blame you
I have not followed the http-r thread, will it run on WOS or WAMP or any other portable PHP implementation? ( I really don't want to "install" anything in Windows)
I haven't investigated that and am not familiar with WOS or WAMP but I looked through most of the HTTP-R code in some depth a few days ago and it was all fairly basic PHP (though it was using some fairly new object-oriented features) so I don't see any reason why not. I'm not sure off-hand if there are any min requirements for what it might need out of an http server but I didn't see anything unusual there, either.
It'd probably be best to ask that question over on the HTTP-R thread. You'll get better info and responses will be in a logical place for anyone looking to for that info in the future.
