Phil Flynn brought to my attention that pdf files couldn't be viewed when saved in RedGloo's filesystem. This came as a surprise to me, as I definately could view them. I tried for sanity sake to view the file using IE (I use Firefox) and it didn't show…
This really surprised me, and I tried to look for several options. By chance I found a MS bug report where it was tied to the https protocol (MS claiming it as expected behaviour). I tried to view the pdf file using the http protocol. This worked!
I have now removed https from the default url, and only use https for login purposes. This is something I wanted to do for some time, but didn't get around until now…
