how to clear a specific header in libcurl

Question

CURL *handle;
struct curl_slist *slist=NULL;
slist = curl_slist_append(slist, "X-libcurl: coolness");
slist = curl_slist_append(slist, "Authorization: Bearer retrffhj");

curl_slist_free_all(slist); /* clears all header list */

How can I clear the header with key Authorization and rest header information should be retained as it is.

clear the entire list
make a new list with the header(s) you want in it
use the new list

I tried that, after clearing the entire list and preparing new list, which gives me Bad Request response. – MUNEERPASHA GADAD Feb 15 '18 at 14:08
that could be a totally separate issue though, show us your code and we might spot something - or not – Daniel Stenberg Feb 15 '18 at 18:28

list = curl_slist_append(list, "Accept:");

If you add a header with no content as in 'Accept:' (no data on the right side of the colon), the internally used header will get disabled.
