Re: curl follow location method

Thank you very much for your quick answer Daniel and your links.

Now (in my test case, I try to POST an empty body):

> curl --data '' --location 'http://localhost:8000/follow-redirect'

Works perfectly : I see a POST then a GET.

> curl --request POST --data '' --location 'http://localhost:8000/follow-redirect'

As designed, I can see the warning message "Note: Unnecessary use of -X or --request, POST is already inferred."
I see a POST then a POST, as designed once again.

I genuinely thought that the "--request" was unnecessary but it also has impact of --location (as mentioned in the docs btw)

It's clear now and I better understand the man message about -request "Normally you do not need this option. All sorts of GET, HEAD, POST and PUT requests are rather invoked by using dedicated command line options.".
I should use the dedicated method instead of --request.

I just have a final question, mainly theorical: if there is no dedicated option for a method (I think specifically of DELETE), the only option to use such a method is with -X/--request.
In that case, combining --request and --location, I won't be able "to test" a redirection with a GET method? The --request will force all subsequent request to use DELETE?
My question is rather theorical, I'm asking for any new feature!

Once again, thank you for your work, curl rocks!

Let me first mention two blog posts of mine on related topics:

> $ curl --verbose --request POST --location 'http://localhost:8000/follow-redirect'


Now you can read that second blog post and ponder about your use of "--request
POST" in this command line! ;-)
