I am trying to specify a page for 404 request but it is not working. Here
apache is acting as a reverse proxy which forwards the request to tomcat. I
am not using any virtual host configuration. Below is my configuration that
I am using

<LocationMatch "^/(application|app)">
        ErrorDocument 404 /application/abc/def.htm
</LocationMatch>

Apache is also hosting few php pages but /application and /app goes to
tomcat.

This seems definitely wrong :) What status code do you get if you make a
query by yourself using curl/wget/etc.. ? Moreover, what version of httpd
are you running? I'd suggest also to increase LogLevel to trace8 (if
possible or if you have a test environment) to track down what httpd is
doing (https://httpd.apache.org/docs/current/mod/core.html#loglevel).

Hello Luca,

Thanks for your solution. This pretty much took care of the problem. But I
noticed that on even 404 error apache is not showing 404 but it is showing
200 in access log. Is it correct?

By default mod_proxy does not interfere with the response from the backend,
passing it directly to the client. If you want to force mod-proxy to
override error responses (like 40X, 50X) you'd need to set
ProxyErrorOverride (
https://httpd.apache.org/docs/current/mod/mod_proxy.html#proxyerroroverride
).

Hope that helps!
