Comment:
I have a setup where I have apache forward port 80 to port 8000, and Sage
runs the notebook on port 8000. I also use the server_pool option. I
applied this patch to a slightly modified 4.5.2. I logged in. When I
tried to open a new worksheet, I got the following error in the log (and I
got an error page in the browser):
