Hi All, I have improved this feature by allowing the end user to add application contexts (a string containing application name, version, etc) together with the domain names:
A sample scenario: - Consider a Tomcat cartridge (single tenant or multi-tenant). - A given server instance would contain a collection of applications. - User would map a domain name to a subscription. - This would generate a mapping as follows (sample): https://some.organization.org/ -> http://lb-host:lb-port/ - Since this server contains multiple applications, the end user might need to access his application as follows: https://some.organization.org/application-name/version/file-path - However if we consider "application-name/version" as the application context, we could allow the domain mapping to include it together with the domain name. - The resulting would allow the user to map domain names as follows: some.organization.org/file-path -> http://lb-host:lb-port /application-name/version/file-path Updated API methods: 1. Add subscription domains: Send a POST request to the following URL with tenant credentials to add subscription domains: POST https://sm-ip:sm-port /stratos/admin/cartridge/{cartridgeType}/subscription/{subscriptionAlias}/domain/ { "domainName": "some.oragnization1.org", "applicationContext" : "application-name-version-etc" } 2. Get subscription domains: Send a GET get request to the following URL with tenant credentials to get existing subscription domains: GET https://sm-ip:sm-port /stratos/admin/cartridge/{cartridgeType}/subscription/{subscriptionAlias}/domain/ 3. Remove subscription domains: Send a DELETE request to the following URL with tenant credentials to remove a given list of domain names: DELETE https://sm-ip:sm-port /stratos/admin/cartridge/{cartridgeType}/subscription/{subscriptionAlias}/domain/ { "domainName": "some.oragnization1.org" } Thanks On Wed, May 7, 2014 at 3:23 AM, Nirmal Fernando <nirmal070...@gmail.com>wrote: > Cool.. thanks Imesh.
