--------------------------------------------
Summary: Single cookie header should be sent for multiple cookies
Key: HTTPCLIENT-2331
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2331
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Reporter: Nikhil Chaudhari
Attachments: DemoServiceOneController.java, DemoServiceOneLogs.txt,
DemoServiceTwoController.java
Single cookie header should be sent for multiple cookies
*Use case* -
When *Cookie* header is added explicitly using {*}setHeader{*}() method and
there exists multiple cookies in cookie store (BasicCookieStore), then for this
use case two Cookie headers are sent by HttpClient.
*Expectation* - Single Cookie header should be sent by Apache HttpClient where
all cookies should be separated by semi-colon
*Actual* - Two Cookie headers are sent by Apache HttpClient, where in cookie
set using setHeader is sent as one cookie Header and cookies in
BasicCookieStore are sent in another Cookie header wherein value is all cookies
separates by semi-colon.
*Steps to reproduce -*
# Setup two microservices
# 1st microservice will set custom Cookie header as part of API request to 2nd
micro service.
# 2nd microservice will respond back with two Set-Cookie headers
# First time when call is made from 1st micro service to 2nd micro service
only custom cookie header will be sent and BasicCookieStore on 1st microservice
will be updated with cookies that we got from 2nd microservice
# Second time when call is made from 1st micro service to 2nd micro service
both custom cookie and cookies from BasicCookieStore will be sent as separate
Cookie headers.
