Increase Proxy Timeout in Apache

This can be useful to increase for long running scripts (e.g. very long imports and exports)

1. Create an include file in /var/local/enhance/apache/vhosts e.g. /var/local/enhance/apache/vhosts/proxytimeout.conf

2. With the following content:-

TimeOut 600
ProxyTimeout 600

3. Restart the webserver (graceful via the UI) and it should have the increased timeout value.
