Bug #: 51725
Summary: Multiple Range: request accepted as "Range: n-m"
Product: Apache httpd-2
Version: 2.1-HEAD
Platform: All
OS/Version: All
Status: NEW
Keywords: RFC
Severity: normal
Priority: P2
Component: Core
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Created attachment 27436
--> https://issues.apache.org/bugzilla/attachment.cgi?id=27436
Multiple Range: request lines trace
Multiple Range: request as
Range: bytes=0-1
Range: 2-3
seems syntactically invalid, so the second Range: should be ignored.
(RFC 2616,14.16 Content-Range)
Apache seems to (correctly) coalesce the request to
Range: bytes=0-1,2-3
which IS syntactically correct, and processed accordingly.
Open issue: how should we handle and/or coalesce multiple Range: lines?
(classical Set-Cookie: have had the similar problem, having "," as data)
Trace on httpd.apache.org (Apache/2.3.8) follows:
===========
Requesting as
> Range: bytes=0-1
> Range: bytes=2-3
yielding only the first Range: being accepted.
