17.1.4. HTTP Protection
HTTP protection assures protection at HTTP level, to prevent accessing files stored in
TB
OX
LT2
using
HTTP protocol. Typically when displaying HTM files with a browser.
Once HTTP security is activated, each file building the web site must be assigned an access level.
In folder "Web and Reports files", right click each file:
ALL files (.twa, .htm, .twf, .gif, ...) composing a view must be given an access level:

Level 0: the file is always visible and does not require a login. Typically a home page.

Level 1: the file is visible by user “Read only”, “Read/Write” and “Engineer”.

Level 2: the file is visible by user “Read/Write” and “Engineer”.

Level 3: the file is visible by user “Engineer”.
Once HTTP protection has been activated (and sent to the RTU), when connecting to
TB
OX
LT2
using a
browser you are prompted to login to open a file with access level 1, 2 or 3.
To create the Login, see chapter 17.3. below.
When several PC’s connect to
TB
OX
LT2
, a login is required for each PC.
Different sessions of the same browser on one PC use the same login.
