Bug #: 51253
Summary: use_server_errors for status 401 does not forward
WWW-Authenticate
Product: Tomcat Connectors
Version: 1.2.31
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: isapi
AssignedTo: dev@tomcat.apache.org
ReportedBy: rainer.j...@kippdata.de
Classification: Unclassified
When using server generated error pages (use_server_errors) and status code is
401, we need to forward the original WWW-Authenticate header to the client. For
example mod_proxy does it that way.
I fixed the problem in r1126561 for mod_jk / Apache. I didn't yet fix it
completely for IIS. There is a new TODO in jk_isapi_plugin.c, see
"start_response()". If anyone likes to fix it for ISAPI, there is already parts
of the fix in start_response(), but the missing part is described in the
following TODO around line 960:
TODO: we need to save a copy of header_values[h]
for later reuse in write_error_message()
which is called later on form HttpExtensionProc
because of use_server_error_pages.
Actually I didn't verify the problem for ISAPI, so that might be a good first
step.
Regards,
Rainer
