Webserver
The webserver setup page contains the settings needed to make the web server
listen on another port in addition to the default 80 (http). The alternate port can also
be configured to function as a low-bandwidth server.
Extra webserver port
– To connect to the Extra webserver port the URL should
have a colon ‘:’ followed by the new port number, i.e.
http://10.10.10.30:8080
where
10.10.10.30 is the IP number or DNS address of the SREA-01 unit and :8080 the
new port.
Compression on web pages
– (Only used for the Extra webserver port) is used to
improve the data transfer for low bandwidth connection, such as modem connection.
SREA-01 will check if the connecting web browser supports compressed data
transfers, and then compress the web pages before sending them.
When compression is used the workload of SREA-01 will increase, and that is why
this feature is not enabled by default.
There is an option to disable compression and the pages will be sent as normal web
pages, which always is the case for the standard web server port 80.
If it is set to “force”, web pages will always sent compressed regardless the support
of the web browser. In some cases the information if the web browser supports
compressed data will be altered in the network route, as with Microsoft ISA server
default setting for controlling port 80. To ensure that compressed web pages are sent
anyway the option “force” is set. Most web browsers support compressed data.
Auto update values and status
– (Only used for the Extra webserver port) to
minimize the amount of data transferred over a connection with http-compression.
The data will be read only one time. To refresh values and status of the visible page,
the appearing refresh button at the upper left corner has to be clicked. If the web
browser reload button is used instead, unnecessary data traffic will be generated.
