Sling Scripts cannot be called directly in CQ5.

Question

Hi All,I read the below :Within Sling, scripts cannot be called directly as this would break the strict concept of a REST server; you would mix resources and representations.If you call the representation (the script) directly you hide the resource inside your script, so the framework (Sling) no longer knows about it. Thus you lose certain features:automatic handling of http methods other than GET, including:POST, PUT, DELETE which are handled with a sling default implementationthe POST.jsp script in your sling:resourceType locationyour code architecture is no longer as clean nor as clearly structured as it should be; of prime importance for large-scale developmentI could not understand much on this. Any detailed explanation on this will be helpful.

Hi,basically it's all about resources. You request a resource and internally sling uses a specific algorithm to determine the script which is used to render the resource in the format you request. Therefor you do not call a script and give the resource to render as paramter to it.For details please see the Sling documentation to the script resolution algorithm [1]. With [2] there is another document available, which might be more readable.Does this answer your question?kind regards,Jörg[1] https://sling.apache.org/documentation/the-sling-engine/url-to-script-resolution.html[2] http://dev.day.com/content/ddc/blog/2010/08/understanding_howsc.html
