Tomcat 4.1.24 - HTTP Status Message..

[David Allison <Da...@orbian.com>]

Hi All,

Recently we upgraded our Tomcat to version 4.1.24..  
We have Apache sitting in front of it providing SSL etc etc..

Since upgrading we've noticed that the status line in HTTP responses has
changed from

HTTP/1.0 200 OK 

to 

HTTP/1.0 200 

I'm not sure that whether the text message on the status line is compulsory
or not but one of our clients systems has been failing since as it calls
HttpURLConnection.getResponseCode() which throws an exception (seemingly
because of the missing text)...

Does anyone know if this text is compulsory in the HTTP response (I haven't
found anything that says clearly either way) and also why Tomcat was changed
this way.. Was there a particular reason, is there any fix to this problem
or is Tomcat still acting correctly (I suspect it is)..

Thanks for your help

Dave

Re: Tomcat 4.1.24 - HTTP Status Message..

FYI: http://issues.apache.org/bugzilla/show_bug.cgi?id=19480

However, contrary to that bug report the Reason Phrase is not mandatory 
according to the spec (well, to be picky, it is mandatory but the phrase 
can be zero bytes long):

HTTP1.1 spec:
http://www.w3.org/Protocols/rfc2616/rfc2616.txt
<snip>
Status-Line = HTTP-Version SP Status-Code SP Reason-Phrase CRLF
...
Reason-Phrase  = *<TEXT, excluding CR, LF>
</snip>

The * in the BNF grammar used means any positive number (and including 
zero).

Additionally, the reason 'OK' for code 200 should not be assumed as the 
server can choose to change this phrase to the local language.

Another upgrade beckons...

HTH,

Jon
