Plus, apache, nginx, IIS? What are you using, this may also have additional overhead associated with it (very tiny, but enough).

> My secondary question is whether any httpd gurus have recipes for redirecting by agent string from low quality images to high quality. So when AGENT =  "Pinterest/0.1 +http://pinterest.com/" and the URL matches a pattern redirect to a different pattern. For example:

> http://nzetc.victoria.ac.nz/etexts/MakOldT/MakOldTP022a%28w100%29.jpg

> to

> http://nzetc.victoria.ac.nz/etexts/MakOldT/MakOldTP022a.jpg
