Anas Quazbary created HTTPCLIENT-2382:
-----------------------------------------
Summary: Apache HttpClient removes the `Content-Length` header
from a DELETE request even when the request has a body and the header is
explicitly set.
Key: HTTPCLIENT-2382
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2382
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Reporter: Anas Quazbary
Fix For: 5.3.1
*Describe the bug*
**
_(Usage via http4k-client-apache 5.29.0.0 with Apache HttpClient 5.3.1)_
**
When using Apache HttpClient (via http4k in Kotlin), I noticed that the
{{Content-Length}} header is removed from DELETE requests, even when:
* a body is explicitly set, and
* the header is manually added to the request.
As a result, the request is rejected or mishandled by the server expecting the
header (e.g., visible via ngrok).
*To Reproduce*
Steps to reproduce the behavior:
# Create a {{DELETE}} request with a JSON body and explicitly set the
{{Content-Length}} header.
# Send it using Apache HttpClient (via http4k).
# Observe the outgoing request (e.g., via ngrok or a proxy).
# {{Content-Length}} is missing.
kotlin :
{code:java}
val request = Request(Method.DELETE, "https://xxx.ngrok.io";)
.header("Content-Type", "application/json")
.header("Content-Length", "16")
.body("""{"some": "data"}""")val client = ApacheClient()
val response = client(request) {code}
Expected behavior Either: Apache HttpClient should honor manually set
Content-Length when a body is present, or automatically compute and include it
when a body is given, even for DELETE requests.
Thank you for your time and assistance. Please let me know if you need any
additional information to help diagnose this issue.
