Executes HTTP load test on specified endpoint. You can also provide number of requests (n) that will be sent to your endpoint. This tool can help to check locally if our app can handle multiple concurrent requests. Currently webfren allows to sent only GET requests.

Example

Command

$ webfren http-load-test https://example.com 100

Result

Runs Load Balancer handling requests load to specified server addresses. This tool can help to check locally if our app will work correctly when load balancing mechanism will be introduced. Currently requests are sent ro randomly selected server.

Example

Command

$ webfren load-balancer 9000 "https://example.com|https://example.test.com"

Result on user request on http://127.0.0.1:9000:
