webserverinfo
ITEM
,
RESULT
The webserverinfo statement retrieves additional information about the web server and the current browser request.
Parameters
This statement has two parameters:
item – specifies what additional information should be retrieved.
result – field or variable where the retrieved information will be placed.
Description
This statement retrieves additional information about the web server and the current browser request. This statement only works on Panorama X Server, and only when an external web server is being used (see Using an External Web Server). For example, this code could be used to find out what external web server software is running:
local serverSoftware
webserverinfo "SERVER_SOFTWARE",serverSoftware
// variable serverSoftware will contain something like --> Apache/2.4.48 (Unix)
The webserverinfo( function can also retrieve the same information, like this:
let serverSoftware = webserverinfo("SERVER_SOFTWARE")
The available items that can be retrieved include:
QUERY_STRING – The information (if any) following the “?” in the URL for this request (for example ColoradoHotels~byCity~Aspen
).
SERVER_SOFTWARE – The name and version of the information server answering the query (for example Apache/2.4.48 (Unix)
).
SERVER_ADDR – The IP address of the server for this URL (for example 207.35.76.24
).
SERVER_ADMIN – The administrators e-mail address for this server (if it has been set up. (for example webmaster@myserver.org
).
SERVER_NAME – The servers host name, DNS alias or IP address. (For Apache the name appearing on the relevant ServerName directive (may be in the general sec- tion or a section) (for example `www.myserver.com)`).
SERVER_PORT – The port number on this server to which this request was directed (for example 80
).
SERVER_SIGNATURE – The HTML string that may be embedded in the page to identify this host (for example Apache/1.3.29 Server at jim-reas- computer.local Port 80
).
SERVER_PORT – The port to which this request was directed (for example 80
).
REMOTE_ADDR – The IP address of the host making this request (for example 207.35.76.27
).
REMOTE_PORT – The port number used by the remote host when making this request (for example 4325
).
REQUEST_METHOD – The method used for this request for HTTP “GET”, HEAD" or “POST” (for example GET
).
HTTP_ACCEPT – The MIME types the requestor will accept as defined in the HTTP header (for example * / *
).
HTTP_ACCEPT_ENCODING – The compression types the requestor will accept as defined in the HTTP header (for example gzip, deflate;q=1.0, identity;q=0.5, *;q=0
).
HTTP_ACCEPT_LANGUAGE – The LANGUAGE types the server is requested to accept as defined in the HTTP header and typically used for content negotiation (for example en-us
).
HTTP_CONNECTION – The type of connection as defined in the HTTP header (for example keep-alive
).
HTTP_HOST – The base URL of the host (for example www.myserver.com
).
HTTP_REFERER – The URL of the page that made this request. If linked from e-mail or manually entered this value is NULL. (Depending on your server settings this may be disabled, in which case the value will always be NULL. Also, many browsers are removing or limiting the information provided by this item.) (for example http://www.samplesite.com/ stuff.html
).
HTTP_USER_AGENT – The browser id or user-agent string identifying the browser (nominally defined by RFC 1945 and RFC 2068). For a list of current browsers see: http:// www.zytrax.com/tech/web/browser_ids.htm (for example Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko)
).
Note: Some of these options may not be available on all servers.
