This PR fixes a bug in
org.springframework.http.HttpHeaders
class.It was not possible to delete/clear the
Host
header before this fix.This bug was first introduced in this commit (in 2018): 5bbbc82#diff-e2d6218e6585f8b7e32682f6f8f7aed22dbd76d862ec92e86e0902243889556aR1020
After that commit, the deletion logic line in
setHost()
method started to look like this:remove(HOST, null)
Although for all other methods/headers it looks like this:
remove(CONTENT_TYPE)
,remove(ETAG)
, etc.And for
setHost()
method it also should be the same:remove(HOST)
I've also added a test for this case. Feel free to rollback my 1-line fix in
HttpHeaders
and check thatHost
header is not cleared indeed.
