KB No. 2677: PROXY CANNOT RESOLVE SHORT NAMES (APPEND_DOMAIN)

When resolving internal sites through the proxy, error messages may appear.

Symptom

When resolving internal sites through the proxy, error messages may appear.

Short domain names cause errors from the proxy, which considers these domains to be incomplete.

Example: http://monapplicationweb

Steps

Theappend_domaindirective will automatically add the DNS domain name to enable internal sites to be resolved through the proxy.

Example: http://monapplicationweb.company.local

The directive will be added in theProxy Cache QoSmodule (or in theSettings > HTTP Proxysection for customers who have not subscribed to the module).

Here is how the directive appears in theManual Configuration > Start of Filesection:

The syntax is therefore as follows: append_domain .DNSDomainName.

You can find this information in the/etc/resolv.conffile: the name is indicated in the "search" line.

Example: search company.local

Validation

By specifying the short domain name, the DNS domain name will automatically be added as a suffix so that resolution can take place through the proxy.
