Webserver issue

[Andrew Valentine]

Hi there,

Not sure if this the right place for this, but any advice greatly
appreciated.

My organisation uses Munki and AutoPkg, and has been using the following
AutoPkg recipe to keep ImageJ up to date:

https://github.com/autopkg/jessepeterson-recipes/blob/master/NIH-RSB/ImageJ.munki.recipe

This was generating error notifications via AutoPkgr. I raised this as an
issue with the author of the recipe on GitHub:

https://github.com/autopkg/jessepeterson-recipes/issues/8#issuecomment-106905875

The author response was:

So the http://rsbweb.nih.gov/ webserver A) does not use ETags, B) does not

Is anyone on this list able to advise and/or fix?

Hi Andrew,

As a workaround, you could use mirror.imagej.net, which mirrors
imagej.nih.gov daily, and behaves more properly.

Curtis
