[jira] Created: (TS-190) Malformed response when total response
headers size exceed MIOBuffer block size
Malformed response when total response headers size exceed MIOBuffer block size
-------------------------------------------------------------------------------
Key: TS-190
URL: https://issues.apache.org/jira/browse/TS-190
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Steve Jiang
Assignee: Steve Jiang
Fix For: 2.0.0a
If:
1. The origin response header size exceeds MIOBuffer block size (default 4K)
2. TS is chunking/dechunking the response (e.g. HTTP/1.0 origin, HTTP/1.1 client or vice-versa)
TS will only send the last block of the header and the response to the client. This results in a malformed response because the first 4K includes the status line.

Steve Jiang updated TS-190:
---------------------------
Attachment: TS190_sjiang.diff
Added patch to keep references to start of chunked/dechunked buffers to avoid blocks from being released before buffer readers are allocated.
