Installation (requires node.js, which comes with npm):

git clone https://github.com/chesles/test-server.git
cd test-server
npm install
npm start

If all goes well you'll have a server running on port 2700

Make a request take longer with the delay parameter:

curl localhost:2700?delay=2000

enforce unique parameters between requests with enforce_unique=true and unique_keys (a comma-separated list).

Once this request is made

curl -v localhost:2700?enforce_unique=true&unique_keys=id,username \
  -d  "id=1" -d "username=foo"

This one will be OK:

curl -v localhost:2700?enforce_unique=true&unique_keys=id,username \
  -d  "id=2" -d "username=bar"

...and this one will return a 500 error (because id=1 has already been passed:

curl -v localhost:2700?enforce_unique=true&unique_keys=id,username \
  -d  "id=1" -d "username=blah"

Kill & restart the server to clear the set of values that have been seen.

Pass a location and an optional responsecode parameter to make test-server return a redirect:

curl localhostT:2700 -d location=https://google.com -d responsecode=301

responsecode defaults to 302 if location is present.
