[1.2.4] Issue with memcache on Heroku platform

[Jan Muller]

Hi, is anybody here, who has an app deployed on Heroku and using memcache? I have problems with connection to memcache servers. My configurtaion is following:

%dev-remote.memcached=enabled

%dev-remote.memcached.host=mc10.ec2.northscale.net:80

%dev-remote.memcached.user=app3089238%40heroku.com

%dev-remote.memcached.password=some_password

I copied the auth data in exact form as they gave to me. I had to add explicitely port 80 to host line, because without it, play threws Exception. But still, it is not working

My log:

Problem solved:

Worked for me, too, thanks :)  Sometimes it's the obvious ... :)

Any idea how to configure this without specifying the memcached server/user/password directly in the source code?

I know Heroku exposes this as enviornment vairables via heroku config ... can Play read these directly?

[Gambo]

Yes you can via:

memcached.user=${MEMCACHE_USERNAME}
...
