Inquisit Web shows old version of updated image file

Blackadder — Fri, 06 Mar 2015 10:32:00 GMT

Hi All,

we have set up an Inquisit Web experiment here: http://research.millisecond.com/psyinstmzweb1/ExperimentRatingScales.web

Just now, I changed one of the image files ("TEXT_welcome.bmp") by deleting the file and reuploading. When I click on said file in the web experiment managing backend, the new file is displayed. However, when running the experiment, the old file still shows up. I tried this with the Java start method as well as the Firefox plugin.

What happens?

Best wishes, Malte

A quick update: it took 4 hoursfor the new file to show up. Your guess about some router-level caching was probably correct. Thanks a lot!

Bye, Malte

Yes, that is exactly the correct file. The file that is getting served to me is not this file but the previous version.

So I'll just wait then and see if the correct file shows up at some point.

Thanks, Malte

The file that I'm getting served is https://www.millisecond.com/myaccount/scripts/psyinstmzweb1/ExperimentRatingScales/TEXT_welcome.bmp (I don't know if that's the correct, "new" one or not, but that's what the server has afaict).

The only other possibilities I can think of are:

(1) The new image wasn't fully uploaded, i.e., you uploaded it via the web script wizard but then mistakenly hit "cancel" instead of "finish" (I consider this unlikely).
(2) There's a caching proxy / webcache somewhere along your network path to the millisecond server that still serves the old file. Nothing you could do about that except waiting for it to flush / update its cache.

Tried that, didn't help. Neither did using a new browser or activating privacy mode. I even installed Firefox to try it via the Firefox plugin. I had *never* before run the experiment from a Firefox instance. Could there be another reason?

Presumably your machine still has the old (wrong) image cached locally. Clear its temporary / temporary internet files / browser cache and it should be fine.
