Is there a way I can read the user agent or something similar to determine whether the person is using IE, Mozilla/Netscape, Opera, Safari, etc?

I know that Rails 1.1-RC1 has many new features but it also seems to fix numerous bugs found in Rails 1.1. So for new projects--say a small (<=10 product) ecommerce website set to launch "any day now", should we use Rails 1.0 or 1.1-RC1? Which is more bug-free? I heard 1.1-RC1 gets rid of the ''white screen of death'' but I''m wondering if any new bugs

...y and no other alternative exists, make suggestions for updating the NAC specification in order to better match the LLVM IR. 4) We expect that the working NAC backend will be able to process realistic, large-scale ANSI/ISO C codes. We suggest that you use the CHStone test suite: http://www.ertl.jp/chstone/ for evaluation; all these codes should produce valid NAC. Please use clang for C-to-LLVM translation. You may choose to use the tblgen tool for backend development. Among the existing LLVM backends in the official release, the PTX backend may be considered somewhat close to NAC...

What happens if multiple requests are handled concurrently by ActionPack? Assuming that the code I execute in my controller methods is thread safe, is this ok? If not -- what happens? The following makes it sound like the issue is
