External requests allowed on ports other than 80?

Hi,

I've been asked on my blog posting whether it's possible to send e-mail via an external service provider such as Amazon or Gmail. But this raises the more general question of what requests are allowed from applications deployed on Cloud Foundry? Port 80 requests seem fine, but what about others? SMTP on port 25 for example.

Thanks,

Peter

Currently outbound access is limited to http and https through proxies. The proxy information will be in the environment for your application under http_proxy, https_proxy, and no_proxy.

 

We will continually look on ways to improve the product and the service, so please keep the feedback coming.

For Java applications, the common proxy system properties are predefined (http.proxyHost, http.proxyPort, https.proxyHost, etc)

But how should we send mails then?

This is bothering me too and a blocker :-(

I would think this would be handled as a service. This may be a differentiator between hosts. We may start to see providers offer services like outgoing mail and apple push notifications as services.

It would be nice if cloudfoundry got an smtp service working soon. In the meantime we could always use something like the rest api here:

But it would be better to just be able to use javamail...

I have a Spring Integration application that I would like to deploy to Cloud Foundry where the application accepts incomming requests on a port other than port 80.  Is this possible with Cloud Foundry?

Hi Ted,

  Please note that for spring applications a tomcat container is provided and configured and you will not 

  have control over which port the container is listening on.  You application in the configured url

  (typically <appname>.cloudfoundry.com) can received traffic on http (80) and https (443)  and 

  cloudfoundry infrastrcuture (front-ends and router) will route the traffic to your application.

  Best Regards,

Is there a way to disable http(80)?

Peter,

There isn't a way to disable HTTP. One option is to inspect for SSL http headers in your app, and redirect the user to https if they don't exist.

To see the difference in http headers compare:

http://gho-env.cloudfoundry.com/

https://gho-env.cloudfoundry.com/

Specifically:

sslclientcertstatus NoClientCert
sslclientcipher SSL_RSA_WITH_RC4_128_SHA, version=TLSv1, bits=128
sslsessionid 925B7E28AE0148050B3E3A41B0F2B76FD57E8795643E0C88455145F9B9C60A7B
