Comment 17 for bug 607961

@Martin
Thank you for the thoughts.

"I'm pretty sure you could do this using mod_rewrite in a way that does
not need per-api-version configuration." OK, but neither does what I outlined. Is there an advantage of using mod_rewrite instead? Would it be shorter or simpler somehow?

"It looks like etags are being attached to a lot of files that have per-revision file names and that could equally well be just said to never need revalidation. What's the desire to still use it?" Yes, the only file that should need it is the "head" devel version.

The importance of wadl cacheing on devel might be minimal. The only practical usage of devel I know about other than early testing is for our JS, which doesn't need wadl. Conclusively determining that devel doesn't need efficient wadl cacheing in the client would probably require a bit of log sniffing, but if we did, that would radically simplify that requirement.
