Thoughts on my little project

The other day I was working with some VoIP phones and tried setting up some remote phonebooks ( xml files stored on a server somewhere ). I struggled to get things to work and documentation was confusing and very minimal.

I thought wouldn't it be great if you could just point it to an url and then see the requests that the phone makes to the url.

So I thrown something quickly together.

If you go to the url, click the button at the top of the page.
On the next page you see a url, this is the url you need to send the request to ( can be anything, you could just paste it in another browser window ). 
If any request is made to that url, the first page will automatically load the request data.

Here is the url: https://http.stephangerlach.com/

Could also be used for other things like when working with Arduino type boards or checking incoming webhook calls.

Any thoughts of helpfulness?

Thanks
