We have multiple load balanced instances of a thredds service published in both (http and https). When a dataset requires authentication the challenge is made through https, and data access is coming back to http.
This is my test. My client and server are in the same side of the firewall ```bash[antonio@ui ~]$ wget -O /dev/null http://www.meteo.unican.es/thredds/fileServer/VALUE/Renalysis/NCEP/NCEP_Z925.nc --2015-12-18 19:28:25-- http://www.meteo.unican.es/thredds/fileServer/VALUE/Renalysis/NCEP/NCEP_Z925.nc

I agree, an Apache front end is a simple and standard thing to do.AFAIU, the user still is using SSL encryption, its just that Apache is doing that instead of Tomcat. So it would be good for any of us to make some measurements comparing large binary data transfers.On Fri, Dec 18, 2015 at 10:42 AM, James Gallagher <jgallagher@xxxxxxxxxxx <mailto:jgallagher@xxxxxxxxxxx>> wrote:On Dec 18, 2015, at 9:06 AM, Steve Ansari - NOAA Federal <steve.ansari@xxxxxxxx <mailto:steve.ansari@xxxxxxxx>> wrote: Sure - I'll follow up offline.

That any proxying, whether AJP or other, would be hidden. I have had problems in the past getting AJP proxying to work, if I need to do that. Can you send me (offline) the part of you httpd.conf where you proxy over to tomcat using AJP?We have had good success using Apache & AJP. Apache as a front end provides a number of options, particularly WRT authentication and this might provide for a compromise should HTTPS be too much of a bottle neck. I have not tested the impact of HTTPS compared to HTTP (it would be easy enough to do using simple file transfers).

My question is can the TDS work with https? If so, can you point me to any documents or what changes, if any, need to be made to use https.
