Symlink and Static Resource

Can you tell me the differences between:

- Weblink
- Symlink
- Static resource

??

Weblinks are links to other resources that use a redirect header. Symlinks forward to the content (not a redirect). Static resources are linked to actual physical files on the filesystem, with metadata contained in the database.

il_dandi,

Please read the documentation: http://svn.modxcms.com/docs/display/revolution/Resource

Excuse me but I don’t know 2 differences

(note that I’ve tried in manager)

Weblinks: ok opens an exaternal (or internal) URL, for example http://www.google.it


<< Symlinks are similar to Weblinks in that they redirect to another Resource or URL; however, symlinks will persist the current URL. >>

What does that mean?? Can you send me an example??
When do you suggest me to use this??


Static Resource is a link to a fisical file?? We save in DB all file content (PDF, Images.....)
When do you suggest me to use this??


Thanks
