Mailing List Archive: ZServer 1.0b1: spurious colon in HTTP response line

(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>
<HEAD>
<TITLE>Musi-Cal... Concert Schedules: Folk Music, Country Music, Rock Music & 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
*** HTTPResponse.py.~1~ Tue Apr 13 15:21:12 1999
--- HTTPResponse.py Wed Apr 21 09:05:00 1999
***************
*** 146,150 ****

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

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