For Ubuntu 12.04, apt-get finds libmemcached6 which *might* work (I'm not
sure about backwards compatibility, and memcached can be a bit "touchy".)

ProxyPass and ProxyPassReverse do string manipulation of the URL. This
is your non-working example:
ProxyPass / http://localhost:8080/kdah
ProxyPassReverse / http://localhost:8080/kdah
The first line says "Replace the string '/' with the string
'http://localhost:8080/kdah' at the start of the URL". So, if the URL
is '/example/page", the replacement is
"http://localhost:8080/kdahexample/page" - does that look right?
The second line says "In certain response headers, replace the string
'http://localhost:8080/kdah' with the string '/' at the start of the
URL". So, if the URL is "http://localhost:8080/kdah/example", the
replacement is "//example" - does that look right?
The reason they don't look right is that the URLs do not match up
correctly. If the URL on the left ends in a '/', so must the one on
the right, or the string manipulations will not work correctly. Eg:
ProxyPass / http://localhost:8080/kdah
ProxyPassReverse / http://localhost:8080/kdah
Neither of these two are right, because the URLs on the left end in a
'/' and the URLs on the right do not. The following should work
correctly.
ProxyPass / http://localhost:8080/kdah/
ProxyPassReverse / http://localhost:8080/kdah/
I wish some note about 'match the slashes' up could go in the
documentation, I follow this simple rule and never have any issues
setting up reverse proxies.
Cheers
Tom

And requesting what? What does the error log and access log say? What
does your HTTP client say?

Provide details. What URL works directly on your backend server? What
URL do you request? Use a client that gives you a proper error

Eric
In my config file i am using only one virtual host i.e is the below one .
My objective is to use without /kd context path so that on typing vicky.com it should get redirected to my to my tomcat application. I tried using the same configuration without /kd context root( only using / slash) in that case page cannot be displayed error comes. Because of which i m forced to used the url vicky.com/kd for accessing tomcat app.
Kindly suggest how to resolve this

Tough to say without a better description of "not able" and thinks
like URL's being used and log entries.
For example -- the first stanza sends /kd/ to /kdah/kd, and the second
stanza sends /kd/ to /kdah/.
Presumably your tomcat doesn't generate the same response for both of
thuse URL's, so only one is going to work.

[users@httpd] Apache - ProxyPass issue -- pls suggest
Posted by vivek aggarwal <vi...@yahoo.co.in>.
Folks,
I am not able to forward the request from apache to tomcat when i am using the following configuration for ProxyPass elements :
<VirtualHost *:80>
ServerName vicky.com
ProxyPass / http://localhost:8080/kdah
ProxyPassReverse / http://localhost:8080/kdah
ErrorLog logs/vicky_error.log
</VirtualHost>
But its working when i am using the context root(any string value eg:- /kd ) as mentioned below
<VirtualHost *:80>
ServerName vicky.com
ProxyPass/kd http://localhost:8080/kdah
ProxyPassReverse /kd http://localhost:8080/kdah
ErrorLog logs/vicky_error.log
</VirtualHost>
Please suggest why is it like that ??????

The error is that libmemcached.so is missing. Reinstall it (which I can't
give you more information about because I can not find any documentation
for osrf_http_translator) and you should be fine.
You could also disable that module: a2dismod osrf_http_translator .
