Allow Overwriting of Content-Length & Transfer-Encoding Headers
---------------------------------------------------------------
Key: HTTPCORE-264
URL: https://issues.apache.org/jira/browse/HTTPCORE-264
Project: HttpComponents HttpCore
Issue Type: Improvement
Components: HttpCore
Affects Versions: 4.1.2, 4.2-alpha1, 4.2, Future
Environment: n/a
Reporter: William R. Speirs
Priority: Trivial
Fix For: 4.1.2, 4.2, Future
Attachments: ResponseContent.diff
Currently the ResponseContent interceptor will throw an exception if the
Content-Length or Transfer-Encoding headers are found in the response. I am
proposing a patch which adds 2 new constructors to ResponseContent. These new
constructors allow ResponseContent to overwrite the Content-Length and/or
Transfer-Encoding headers if they're already found instead of throwing an
exception.
The biggest use I see for this is in a reverse proxy. The response from the
proxied server will already have proper Content-Length and Transfer-Encoding
headers. However, this interceptor throws an exception in this case. The simple
answer is to remove this interceptor; however, I would like to clean-up any
response where these headers might be missing.
The default constructor is to thrown an exception if these headers are found.
