[users@httpd] Re: problem with url encoding for apache server as load balancing
server
Hi,
Just in case people didn't paid attention to the first message, I was
hoping someone knew the answer to this simple apache (2.2)
configuration problem (uri encoding in utf-8 and not in iso..).
Thanks,
Rui

Ok you did not gave me any urls... I thought so, but it was google who
gave based on your indications:

Thanks Eric.
By reading the info urls you gave I was able to identify the problem.
It was just a matter of setting apache to disable url parsing since I
want it as a clean simple load balance server. Just had to comment the
original line and set it as unparsed according:
#JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories
Thanks again,

Look at the jkoptions that talk about URI encoding, or pre-encode your
links, or figure out how to coerce browsers into generating the query
string you want reliably.

Ok Eric,
I have no logs to give you ( I really don't know what you want to be logged).
I will give you an example (value Mérida):
http://apacheserver/myapp?param=M%C3%A9rida
(UTF-8 url encoded) Goes bad! (I don't want to go bad). Meaning bad
that the tomcat cluster translates into wrong/strange characters.
http://apacheserver/myapp?param=M%E9rida
(ISO88591) Goes ok! But that it's not what I want since I want to
encode in utf-8.
http://tomcatA/myapp?param=M%E9rida
(ISO88591) Goes bad! But that's ok cause I don't want no one (apache
or tomcat nodes) to handle iso8591 encodings on url.
http://tomcatA/myapp?param=M%C3%A9rida
(UTF8) Goes ok! And that's ok, cause I want everyone (apache and
tomcat nodes) to handle utf-8 encodings on url.
Please Erik tell me if it's still not clear what's going on. Apache
2.2 Simple load balancing (for the tomcat nodes) with mod_jk, no
special httpd.conf besides the normal worker configuration for load
balancing. Do you recongnize my problem? Do you think it has a
solution?

I still don't see any logs, example URLs, or a clear indication of
what happens when you receive a utf-8 encoded query string.

Re: [users@httpd] Re: problem with url encoding for apache server as
load balancing server
Posted by rui fernandes <rj...@gmail.com>.
Hi Eric,
Thanks for the answer. I am using mod_jk and redirecting everything to
be handled by the tomcat remote servers (apache 2.2 is purely doing
load balancing for the two tomcat nodes of the cluster).
If I call directly my tomcat cluster nodes I have to call with values
url encoded in utf-8 which is ok.
If I encode the parameter values in a url (for example myvalue in
http://myapacheserver/mywebapp?myparam=myvalue_url_encoded) in
iso8859-1 then the request arrives at my tomcat cluster nodes properly
(utf8 url encoded).
If I make the requests to the apache load balancing server in utf-8
(that's what I want) then the request is not properly forwarded by
apache to the tomcat nodes (the values arrive with bad charset
encoding...).
I want any remote client (user or app) to access the apache load
balancing server or the tomcat cluster nodes directly in a
transaparent way. With the same url encoding: utf-8.
I read that Apache by default expects iso8859-1, and I already tried
to configure in the usual way with adddefaultcharset, indexoptions and
so. I thought this was a normal issue with apache with a more or less
straightforward answer... guess I am wrong. I don't think the fact
apache is doing load balancing through moid_jk to a tomcat cluster
should be very important (thought i can be wrong). I would think this
is just a httpd.conf problem.
I hope this extra information helps you or anyone to give me a clue on
how to solve this.
Best,
rui.

It's not simple. IMO It didn't include enough rigorous information
for anyone to comment on.
Were you using mod_jk before you added balancer or mod_proxy_ajp?
What's your current and previous configuration?
What does it mean for apache to "expect" ISO8859-1?
Figure out byte-for-byte what the browser requests and what is
requested by your connector module, and include the information.
