Well, here is the deal:

main domain: main.tld
add-on domain: addon.tld points to main.tld/serv

If i deploy webapp (manager app) to ~/public_html/serv it can be accessed with main.tld/serv immideately, but addon.tld gives nothing until tomcat restart.

Both hosts (domain name) are properly configured, web.xml are ok too. Nothing obvious is wrong (like server is not powered .

Any ideas?
