I wish I could cURL that network request
So OK, you've got this webpage that's making an xhr (XML http request) and you really want to iterate on the results you're getting back from that request. cURL seems like the answer there, but sometimes constructing a cURL request on the command line isn't worth the effort.
Enter Chrome.
In the network panel of Chrome's developer tools you can ctrl-click the request in question and choose Copy as cURL. Presto! Paste it into the cmd line and start iterating on that endpoint!
