Default destination folder of stunnel-*-win64-installer.exe
by Yasuhiro Kimura 13 Jul '23

Hello, If you install stunnel on Windows with stunnel-*-win64-installer.exe, it installs everything under "C:\Program Files (x86)\stunnel" by default. But since it installs 64bit binaries, should default destination folder be "C:\Program Files\stunnel"? Regards.

Using URL Subfolders to redirect traffic to a different service?
by hellmanandrew＠comcast.net 02 Jul '23

02 Jul '23

I want to be able to actually use stunnel as a reverse proxy by running everything through one port. How I want to do that is by using subfolders in a URL like: webpage.net/service1 webpage.net/service2 Basically, every subfolder will redirect to a different IP address or port offered by a server. Just not sure how I should configure this.
