Tool for distributed HTTP benchmarking?

I would like to benchmark a website that our company is developing. It will consist of multiple web- and backend-servers. To be able to properly simulate a large amount of request, I was thinking about using our dev machines (approx 15 Xp/Vista) and a few spare Red Hat servers as benchmarking clients.Is there any tool that would let me set up these machines as slaves/clients, and then control them into performing a combined benchmark and get aggregated results?The benchmark would consist of simulating a normal user logging in and surfing a few ...Read more

http - Fetch API, custom request headers, CORS, and cross-origin redirects

I need to make an HTTP GET request with custom request headers in-browser and process the result as it streams in. The Fetch API is ideal for this:fetch('', { method: 'GET', headers: { 'X-Brad-Test': 'true' }, cache: 'no-store', mode: 'cors'}).then((res) => { const reader = res.body.getReader(); // etc.});This works quite well. Since there are custom headers, the browser pre-flights the request with an OPTIONS request to /resource. I have configured my server to respond with a 204 No Content and the f...Read more

Canonical handling of HTTPS request when SSL not supported

If a client is requesting a domain that does not have a valid CA signed certificate and the server not intend on supporting HTTPS but does support HTTP for this domain, what is the best way to handle this in the web server. Note, the server does handle requests for SSL (HTTPS) on other domains so it is listening on 443.Example where this would apply is for multi sub-domains where the sub-domains are dynamically created and thus making it extremely difficult to register CA signed certificates.I've seen people try to respond with HTTP error codes...Read more
