[Rabbit-dev] why does this image not get compressed?

[Luis Soltero]

hello Robo,

Check out the following url.

Loading Image...&width=800

The header returns as jpeg and the browser displays it fine but the proxy just passes it through with out resampling it.

If, however, you use the following portion of the url
Loading Image...

The image gets put through convert and resampled without issue. For some reason the proxy is getting confused by the
above even though the header being returned indicates that its an image.

Any ideas?

hello Robo,
Check out the following url.

If you do a HEAD '<the url>' and check the header you will find:
Cache-Control: private, max-age=86400

This means that rabbit is not allowed to cache the image and rabbit will
only recompress images that it can cache.

The shorter url is cacheable since it has a different header:
Cache-Control: public, max-age=86400

It would be possible to rework rabbit so that it does not use the cache
for image conversion, but that is nothing I currently have planned for.

OK. that makes perfect sense. Thanks for the explanation.
