[Zope-dev] ZServer 1.0b1: spurious colon in HTTP response line (fwd)

Zopistas:

My brain is apparently fried and it's only 10am.  I originally posted this
to python-dev by mistake.

(Also reported to the bug catcher.)

I'm trying to migrate from ZopeHTTPServer to ZServer 1.0b1.  I was seeing
the ZServer headers turning up in pages generated by the process.  When I
viewed the page source of the generated HTML I saw:

    HTTP/1.0: 200 OK
    Server: Zope/experimental ZServer/1.1b1
    Date: Wed, 21 Apr 1999 13:00:38 GMT
    X-Powered-By: Zope (www.zope.org), Python (www.python.org)
    Connection: close
    Content-Type: text/html
    Content-Length: 7802

    <!-- -*-html-helper -*- -->
    <HTML>
    <HEAD>
    <TITLE>Musi-Cal... Concert Schedules: Folk Music, Country Music, Rock Music &amp; more!</TITLE>
    ...

I run ZServer behind an Apache 1.3.3 running mod_proxy.  Apparently Apache
doesn't recognize the HTTP response when there is a colon following the
version number and adds a simple set of headers itself.  I guess web
browsers either ignore that line or are more lenient in their parsing of the
response.

The following simple patch corrects the problem:

diff -c2 HTTPResponse.py.~1~ HTTPResponse.py

          # status header must come first.
!         append("HTTP/%s: %s" % (self._http_version, status))
          if headers.has_key('status'):
              del headers['status']
- --- 146,150 ----

          if headers.has_key('status'):
              del headers['status']
