Hi,
If we want to fetch the website via temporary URL for plesk, You are having two modes.
1, Quick Preview
2, Limited Preview
Quick preview is the recommended option, presents customer's sites as subdomains of one of your domains. Limited Preview is used in earlier Panel versions; it presents customer's sites as directories under the Panel server. This comes as default. We can change that from plesk control panels from the following location
Tools & Settings > Website Preview Settings.
In quick preview, site can be viewed in the following URL syntax
http://customer-site.com.192-168-0-1.your-domain.com
Here "192-168-0-1" is the IP of your plesk machine, replaced with the dot as dashes.
In Limited Preview, You can fetch the website as temporary URL with the following URL syntax
http://host-name:8443/sitepreview/http/your-domain.tld/
The Limited preview has two major drawbacks: Only authorized users can view such websites and some scripts and Flash animation might not work well on them. hence it is recommend to use this mode only before the Quick Preview is configured.
That is it. Thanks
