Re: [google-appengine] Re: Do I have to implement /_ah/warmup
Jay,
Yeah, I need to import a few packages, so I just wrote an empty handler for
/_ah/warmup so that the import and compiling happen.
Thanks,
Will

[google-appengine] Re: Do I have to implement /_ah/warmup
In Python, they are disabled by default (http://code.google.com/
appengine/docs/python/config/appconfig.html#Inbound_Services), so if
you're seeing them, and your app.yaml is not configured for warmup,
it's likely a bug.
In Java, they're on by default (http://code.google.com/appengine/docs/
java/config/appconfig.html#Warming_Requests), so if you want to
disable them, you can specify in your web.xml:
warming-requests-enabledfalse/warming-requests-enabled
There looks to be a documentation error if your use app.yaml to
configure your Java application:
http://code.google.com/appengine/docs/java/config/appconfig.html#Warming_Requests
says Warming requests are also enabled by default if you configured
your Java application with app.yaml.
http://code.google.com/appengine/docs/java/configyaml/appconfig_yaml.html#Warming_Requests
says In Java applications configured with app.yaml, warming requests
are disabled by default.
I'm not sure which one is true.

[google-appengine] Re: Do I have to implement /_ah/warmup
Worth noting is that the documentation is wrong. The XML-tag to use to
disable warmup requests in Java is warmup-requests-enabled and _not_
warming-requests-enabled.
Maybe you can fix it Nick? :)
