Guys,

I don't know if this is related to

Changes with nginx 0.8.40 07 Jun 2010

*) Bugfix: the "If-Modified-Since", "If-Range", etc. client request
header lines were passed to FastCGI-server while caching.

but since i'm running nginx version: nginx/0.7.65 this is possible.

the thing is I have images that are behind fastcgi and for some reason nginx cache is returning 304 code for clients that never downloaded the image.

so i want know if this is a bug related to 0.8.40 fix if is this will be backported ? if not there is any workaround for this ?

Thanks,
Marcus Maciel

i forgot to say if i try use If-Modified-Since or Last-Modified

at fastcgi_ignore_headers i receive errors

Starting nginx: [warn]: invalid value "If-Modified-Since"
Starting nginx: [warn]: invalid value "Last-Modified"

anyone ?
