2.8.0 version introduced harvesting incompatibility

[cmartinez]

The changes introduced on gn2.8 regarding language codes (e.g. 'eng' insted of 'en') have broken harvesting compatibility with pre-2.8.0 geonetwork versions.

Geonetwork 2.6 tries to connect to /geonetwork/srv/en/xml.search, which has changed to /geonetwork/srv/eng/xml.search in gn2.8.

The 2.8 server sends a HTTP/1.1 301 Moved Permanently response, but this is not handled at all by gn harvester, which tries to directly parse this response as an xml.search response and thus fails.

A fix to don't break 2.6, I think should be update WEB-INF/urlrewrite.xml language rules to use a redirect instead of permanent-redirect, like this:

  <rule>
        <from>^(.*)/en/(.*)$</from>
        <to type="redirect" last="true">%{context-path}$1/eng/$2</to>
   </rule>

After this change, GeoNetwork requires to be restarted.

I'll check if works ok and commit changes so are available for 2.8.1

I am afraid it will not work without changes on 2.6, as the harvester is using POST method, and httpclient doesn't automatically handle redirects for POST (they have to be handled explicitly, getting the redirection address from the response and executing the request again for the new address).

I attach a patch for 2.6 version which solves the problem Warning: it is not a generic patch nor has not been tested thoroughly. Use it at your own risk!
