Apache/mod_jk/Tomcat 404-problem
Hi,
I'm running a webserver with many virtual hosts. The default virtualhost
is the registrar.no virtualhost that has a serveralias to www.registrar.no
I issue the following requests:
http://registrar.no/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
http://www.registrar.no/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
http://192.168.1.10/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
In my logfile I get:
192.168.0.44 - - [03/Jun/2003:10:28:14 +0200] "GET /servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper HTTP/1.1" 404 839 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
192.168.0.44 - - [03/Jun/2003:10:28:19 +0200] "GET /servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper HTTP/1.1" 404 839 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
192.168.0.44 - - [03/Jun/2003:10:28:40 +0200] "GET /servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper HTTP/1.1" 200 0 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
Why do I get a 404 on the two first ones while I get a 200 on the last?
The 404 is generated by Tomcat, so it's obvious that Tomcat kicks in.
While the AJP runs on port 11143, I have a HTTP server instance (from the
same server.xml file) running on port 41143. When I do
http://registrar.no:41143/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
http://www.registrar.no:41143/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
http://192.168.1.10:41143/servlets/servlet/no.registrar.servlets.LagEndreDnsKnapper
they all produce the correct output.
My server is Apache/2.0.46 (Unix) DAV/2 mod_jk2/2.0.3-dev PHP/4.3.1
mod_python/3.0.3 Python/2.2.2 mod_ssl/2.0.46 OpenSSL/0.9.7a with Tomcat
4.1.24
My virtualhost is:
<VirtualHost *:80>
ServerAdmin webmaster@registrar.no
ServerName registrar.no
ServerAlias *.registrar.no
DocumentRoot /home/no/regis_7
CustomLog /var/log/weblogs/registrar.no/access_log combined

Thanks in advance for helping me figuring out this 404.

Not that I know of, short of checking the source or asking on tomcat-dev.

Not that I know of...the "debug" level for JK logging doesn't list the host
headers, as far as I know. I guess you could always tweak the JK/JK2
source to do so, and compile your own version...shouldn't be too difficult.
The other thing would be to check Tomcat's logs when requests come
in...Tomcat should log 404s, etc. just as Apache does, along with the
request URI.
Someone else may have better suggestions. I don't use JK2, but AFAIK name-
based virtual hosting works...I know it works with JK.

Hi John, and thanks for taking your time to help me :)

Right. Is there any way of figuring out whether Tomcat accepts it? Either
way, it seemed to respond equally to requests that were called through the
alias and through the servername

First thing I did was to have a chat with the Apache folks, and they
recommended I had a chat with the mod_jk2 crew as they could not find any
problems.
Is there any way I can monitor what headers are sent to mod_jk2 and what
headers are sent from mod_jk2?
> Also, do you have Apache's NameVirtualHost directive enabled?
Yes, I do. :)

First thing I would do is drop the wildcard from ServerAlias. There's a
very good chance that's an Apache thing...that doesn't necessarily mean
that Tomcat accepts it.
Since your Tomcat instance serves all the requests correctly, the culprit
is Apache not passing the correct host header to Tomcat (or rather, the
host header that Tomcat needs to see). This may or may not be a mod_jk
issue, too.
Also, do you have Apache's NameVirtualHost directive enabled?
