> Content-Length header field may be set twice
> --------------------------------------------

> Key: JCR-3942

> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-jcr-server
> Affects Versions: 2.11.3, 2.13.0
> Environment: Windows 10 64Bit, Java build 1.8.0_66-b17
> Reporter: André Dörscheln
> Assignee: Julian Reschke
> Priority: Minor
> Labels: cand, candidate_jcr_2_12, easyfix, patch, performance
> Fix For: 2.14.9, 2.20.1, 2.22, 2.21.1, 2.18.6, 2.16.7
>
> Original Estimate: 1m
> Remaining Estimate: 1m
>
> In {{ExportContextImpl.java}}, in line 179, the variable hasContentLength is
> set, when the current header-field ist "Content-Length". This variable is
> used some lines below to check, if the header has already been written out.
> The Problem: When "Content-Length" is not the last field of the header, the
> assignment is useless, because it gets overwritten in the next iteration and
> the header is set one time more, than it should be.
> Patch would be to add an if-condition:
> {code:title=Patch}
> if (!hasContentLength)
> hasContentLength = DavConstants.HEADER_CONTENT_LENGTH.equals(name);
> {code}
