Subject Re: Status-Line with no Reason-Phrase
Date Thu, 31 Oct 2002 15:30:50 GMT
I have reported a PR ( 
about mod_jk. Because I am not getting the "Reason-Phrase" in the response.

My colleague Martin Kraemer fixed something in Apache-1.3 (22/07/2002):
Modified:    src/modules/proxy proxy_util.c
   Tomcat with mod_jk2 sometimes omits the Reason-Phrase from the
   response line ("HTTP/1.1 200 \r\n"). It looks like RFC2616 allows this,
   but ap_getline() strips the trailing blank, and that lead to
   an error in ap_proxy_read_response_line() for proxy-requests to
   Tomcat+mod_jk2 servers. (It replaced the NIL after the "200" by
   a space, and so the resulting response line had an extra NL appended).
   Now the SP character which was deleted by ap_getline() is reappended,
   avoiding the erroneous '\0'->' ' change, and preserving RFC2616's
        Status-Line = HTTP-Version SP Status-Code SP Reason-Phrase CRLF
        Reason-Phrase = *<TEXT, excluding CR, LF>
   (thus there is now always a SP after the Status-Code).
May be you need this fix.
