I was looking at the cacheability of my website in zope, and saw that the misc_/OFSP/*.gif images (as in the icon objects) are NOT cacheable because they don't return *any* date info. If they *at least* returned a Last Modified, they'd be cacheable. I looked at the Zope Source and it looks like misc_.py just calls ImageFile objects. Why aren't the ImageFile objects setting these header info bits correctly? I'm not very knowledgable about Zope inside, but this seems like it should be happening. A side effect of fixing this problem would be that the manage screens would suddenly work much faster since the icons would not need to be reloaded EVERY time!! Here is the HEAD info from two ImageFile objects. The first is in the folder images which has a SiteAccess object that forces the Cache-Control object, a normal Image would not have the Cache-Control line. The second is a misc_.py object: checkhead http://docwhat.gerf.org:9673/images/thedoctorwhat HTTP/1.0 200 OK Server: Zope/Zope 2.2.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Wed, 15 Nov 2000 19:06:23 GMT Cache-Control: public, max-age=86400 Connection: close Content-Type: image/png Content-Length: 21717 Last-Modified: Wed, 15 Nov 2000 03:14:17 GMT checkhead http://docwhat.gerf.org:9673/misc_/OFSP/Folder_icon.gif HTTP/1.0 200 OK Server: Zope/Zope 2.2.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Wed, 15 Nov 2000 19:06:37 GMT Connection: close Content-Type: image/gif Content-Length: 903 I have attached by stupid checkhead program.
