• University of Toronto ☛ The HTTP Last-Modified value is specific to the URL (technically so is the ETag value)

  Last time around I wrote about how If-None-Match values (which come from ETag values) must come from the actual URL itself, not (for example) from another URL that you were at one point redirected to. In practice, this is only an issue of moderate concern for ETag/If-None-Match; you can usually make a conditional GET using an ETag from another URL and get away with it. This is very much an issue if you make the mistake of doing the same thing with an If-Modified-Since header based on another URL's Last-Modified header. This is because the Last-Modified header value isn't unique to a particular document, in a way that ETag values can often be.
