Very simple app to do flexible redirections from perts.me to neptune.perts.net/participate/portal.
- Allows https redirects
- Applies path and query string to the new domain
- Install
gcloudand the python tools like all our other app engine projects. See Tools for Web Development for environment setup steps. npm start(or use aliasnpm run server)- Visit localhost:8001 in your browser
Entering a URL in your browser with the https protocol requires a key exchange with that domain, before redirection. So the initially targeted domain needs to have a valid TLS certificate. This is non-trivial with some hosting providers, like GoDaddy.
Deploying to App Engine, which automatically manages free certificates, makes this simpler.
Note: the location of the 301 response will always use https://.
We use this app at perts.me to redirect to neptune.perts.net/participate/portal. Any path or query string should be appended. For example:
| URL | 301 redirect |
|---|---|
| perts.me | neptune.perts.net/participate/portal/ |
| perts.me/XYY | neptune.perts.net/participate/portal/XYY |
| perts.me/XYY?foo | neptune.perts.net/participate/portal/XYY?foo |
Build an app.yaml file with a redirection domain and/or path.
./build_app_yaml.sh neptune.perts.net/participate/portal
Then start the app.
npm start
It should respond with a 301:
$> curl -I http://localhost:8001/foo
HTTP/1.1 301 Moved Permanently
content-length: 0
location: https://neptune.perts.net/participate/portal/foo
cache-control: no-cache
content-type: text/html; charset=utf-8
Server: Development/2.0

To deploy, run the deploy script and specify the project ID and where to redirect. Assumes the App Engine version is "production".
npm run deploy perts-me neptune.perts.net/participate/portal
To deploy to another version for testing:
- Make sure to generate the correct app.yaml file with the intended redirect.
- Use a custom gcloud command. Don't forget
--no-promote!
./build_app_yaml.sh custom-domain.org
gcloud app deploy app.yaml --project=perts-me --version=acceptance --no-promote
