Currently we have a brand spanking new install of 10.2 ArcGIS-Server with the web adaptor installed on a separate server in the DMZ running HTTPS with a purchase SSL cert. We cannot bind both 80 and 443 on the IIS server as it breaks the applications using the SSL for some reason.
We need to install a second on another web server for a 3rd party app that integrates GIS web mapping into its software but cannot do HTTPS, so this will be Web Adaptor #2 using only http 80. Has anyone ever done multiple web adaptors? Are there any caveats to this?
