mod_rewrite with [last] not behaving as expected

Hi All

I've been trying to set up some rewriting rules with mod_rewrite, and
discovered that even with a [last] directive, things aren't quite behaving
as I'd expect.

My config is perhaps slightly unusual, in that I have a default rule that
applies, at the bottom of the rewrite block. The config is something like:

DocumentRoot /var/www/foo/
<Directory /var/www/foo/>
RewriteEngine on
RewriteRule ^foo/foo.xsd /schema/foo.xsd [last]
RewriteRule ^foo/.* /schema/about_foo.html [last]
RewriteRule .* http://somewhere-else/ [R]
</Directory>

Turning on RewriteLog and RewriteLogLevel, I see that a request for
/foo/bar is re-written as an internal redirect to /schema/about_foo.html.
No further rewriting occurs. The problem is that apache decides that it
then needs to start processing /schema/about_foo.html from the top of my
rewriting block, since it too falls within the Directory. It then runs
off, does more rewriting, and goes to the wrong place.

In short, the [last] directive stops this re-writing run, but doesn't
prevent further runs.

Is this behaviour:
a) expected (except by me!) or unexpected?
b) if expected, should we add another mod_rewrite flag to prevent further
mod_rewrites touching the request? (eg [nofurther])

(For anyone suffering the same issue, my workaround was to add a
<Directory> for the schema subdir, with RewriteEngine on, but no rules)

Hello All,

I have some problem with Apache2.0 while sending the response.
When accessing the request from the browser , the response sent is got
properly.
But when I am using a C++ program for sending and receiving the response
I am getting the response with some addional text appended.
The addition text appended is

"<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>200 OK</title>
</head><body>
<h1>OK</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete
your request.</p>
<p>Please contact the server administrator,
you@your.address and inform them of the time the error occurred,
and anything you might have done that may have
caused the error.</p>
<p>More information about this error may be available
in the server error log.</p>
<hr>
<address>Apache/2.0.55 (Win32) mod_jk/1.2.6 Server at dpe1w023 Port
2906</address>
</body></html>
"

In think in case of IE, IE is parsing the response and displaying the
file properly.

Thanks,
Sudhakar

it looks like you've enabled the custom ErrorDocument directive for the
200 error code.

try disabling it.
