In many use cases, it is not wanted to have user accidentaly click on external links and leave the served ZIM content. This could be because the result is unpredictible (reader not implementing this properly) or because the serve user knows there's no backup internet connexion or because there is an induced cost behind external links that doesn't affect served content. using a new flag (`blockExternalLinks`) on `Response`/`setTaskBar`, a piece of JS code is injected into the taskbar code. This code adds a JS handler on all link click events and verifies the destination. If the destination appears to be an external link (1), the link target is changed to a specific URL: ``` /external?source=<original_uri> ``` (1) external is a link that's not on the same origin and starts with either `http:` `https:` or `//`. Server implements a new handler on `/external` that displays a new page (`captured_external.html`) which returns a generic message explaining the situation and offering to click on the link again should the user really want to. This is done by specifically asking `set_taskbar` to not block external requests on that page. This approach allows integrators using a reverse proxy to handle that endpoint differently (rebrand it) 1. `Server` now has an `m_blockExternalLinks` defaulting to `false` 1. `Server.setTaskbar` is extended to support an additional bool to set the variable. 1. `Response` now has an `m_blockExternalLinks` 1. `Response` constr expects an additional bool for `blockExternalLinks`. 1. `Response.set_taskbar` is extended to support an additional bool to set the variable. 1. JNI/Java Wrapper reflects the extensions. 1. New resource file `templates/block_external.js` (included in head_part). Should it be in skin? 1. New resource file `templates/captured_external.html` for `handle_captured_external()` 1. Added a comment on `head_part.html` to help with JS insertion at the right place 1. `introduce_taskbar()` conditionnaly inserts the JS inside the taskbar |
