Sitemap Generator Forum

Hi there,

in my setup, the sitemap generator always reports the current time as the last-modified timestamp for PDF files. Some details:

(1) The sitemap generator is configured to include PDFs in the sitemap, but not to parse them. 
(2) It is set to use the server's response for the last-modified tag.
(3) The server sends the correct HTTP last-modified header, corresponding to the file upload timestamp.

Looks like a bug. Could it be that the sitemap generator doesn't do a HEAD request for files which are not parsed, and then defaults to the current time for the modification tag?

Cheers,

Michael

Hello,

since it doesn't parse the files, it's not requesting it from server and cannot get last-modification date. You can use "Individual attributes" setting to define lastmod date for them instead.

Setting the last-modified dates by hand is a good idea for a limited number of files which don't change often - thanks for the suggestion. But it is also a little tedious, so I'd rather turn this into a feature request then

Getting the server headers without retrieving the file can be done by a HEAD request, and perhaps that's the most efficient way for dealing with files which are not parsed.
