Question

I’m currently getting the info about the files with GET, will it be faster if I rewrite it using HEAD request? Cause I close the connection after the first response.

Answer 1

A HEAD response only includes the HTTP headers but no body – it is generally faster to just use a HEAD if you do not use any information in the body that would have normally transferred in a GET response – if there was no body to begin with it should not make a difference.

Also from here:

The HEAD method is identical to GET except that the server MUST NOT
return a message-body in the response. The metainformation contained
in the HTTP headers in response to a HEAD request SHOULD be identical
to the information sent in response to a GET request. This method can
be used for obtaining metainformation about the entity implied by the
request without transferring the entity-body itself. This method is
often used for testing hypertext links for validity, accessibility,
and recent modification.
