If-Unmodified-Since

Server NGINX
1

It appears from documentation and Googling that nginx supports the
If-Modified-Since header but not the If-Unmodified-Since header; are
there any plans to add support?

Thanks,
Jeff

nginx does not support If-Unmodified-Since.
I believe it’s easy to add it, but are clients which support the header
?

I don’t know an exhaustive list, but I do know that cURL supports it,
which means any program using it for downloads (lots) or using libcurl
(lots) support it. urlib4 supports it as well. I believe wget does too.

I would guess most dedicated downloaders/download accelerators also
support it.

Thanks,
Jeff

The attached patch adds If-Unmodified-Since support.

Cool!

Any chance we’ll see an official 0.8.54 release with this applied?

Thanks,

It will be in the next 0.9.2, and then probably on December 13 or 20 in
0.8.54.
