Summary: once in a while, apache forgets to send headers for a
binary file.
Product: Apache httpd-2
Version: 2.3-HEAD
Platform: PC
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P2
Component: Core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
On a stock build of apache, No modules loaded,
request for a pdf file multiple times, once in a while
the response does not contain response headers.
Note that the same behavior is visible on Apache/2.2.8 also (did not check
2.2.9)
Here is what I did,
|uname -a
SunOS agneyam 5.11 snv_84 sun4u sparc SUNW,Sun-Blade-1000
|file htdocs/test.pdf
htdocs/test.pdf: Adobe Portable Document Format (PDF) v1.2
|(echo "GET /test.pdf HTTP/1.0\n\n";sleep5)|telnet 0 8080 > o
|cat o
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
GET /test.pdf HTTP/1.0
ÛßÞ~}>^#õ¥æcuVêã
*Note the absence of headers*.
This happens only once in 10 times.
Other times, it gives me back the correct response.
