Link header pagination only parsing first rel #5257
Description
Steps to reproduce
$uri_base = 'https://MYDEVORG.okta.com'
$apikey = 'MYAPIKEY'
$uri = $uri_base + '/api/v1/users/?filter=status eq "STAGED"&limit=200'
$method = 'GET'
$headers = @{'Accept'='application/json';'Content-Type'='application/json';'Authorization'="SSWS $apikey"}
PS /> $json = Invoke-RestMethod -Uri $uri -Method $method -Headers $headers -FollowRelLink
PS /> $json.Count
200
PS /> $webreq= Invoke-WebRequest -Uri $uri -Method $method -Headers $headers
PS /> $webreq.RelationLink
Key Value
--- -----
self https://MYDEVORG.okta.com/api/v1/users?limit=200&filter=status+eq+%22STAGED%22
PS /> $webreq.Headers.Link
<https://MYDEVORG.okta.com/api/v1/users?limit=200&filter=status+eq+%22STAGED%22>; rel="self"
<https://MYDEVORG.okta.com/api/v1/users?after=OKTAUSERID&limit=200&filter=status+eq+%22STAGED%22>; rel="next"
PS />Expected behavior
Invoke-RestMethod should follow the next rel link and return additional results.
Invoke-WebRequest RelationLink dictionary should contain both "self" and "next".
Actual behavior
Only the first value from $webreq.Headers.Link is parsed into RelationLink.
