Obtaining client information
You can use the following FileMaker XSLT parameters to obtain information from the Web Publishing
Engine about a web client’s IP address, user name, and password:
<xsl:param name="client-ip"/>
<xsl:param name="client-user-name"/>
<xsl:param name="client-password">
Include these parameter statements in your XSLT stylesheet before the top <xsl:template> element.
You can use these parameters if you need to provide the web user’s credentials when programmatically
loading additional password-protected XML documents while processing the original request. See
“Loading
additional documents” on page 57. next. The web user must provide the user name and password initially via
the HTTP Basic Authentication dialog box. See “When web users use Custom Web Publishing to access a
protected database” on page 17.
For more information and examples of using these three FileMaker XSLT parameters, see the FileMaker
XSLT Extension Function Reference.
Using the Web Publishing Engine base URI parameter
The Web Publishing Engine defines the base Uniform Resource Identifier (URI) parameter to be the host and
port where the Web Publishing Engine is installed. The base URI allows requests for XML data from
FileMaker databases to be resolved in relation to the Web Publishing Engine host.
To access the Web Publishing Engine base URI, include this statement in your XSLT stylesheet before the top
<xsl:template> element:
<xsl:param name="xml-base-uri"/>
You can then use the base URI for the current stylesheet via the $xml-base-uri variable whenever you need to
make an additional request for FileMaker XML data. For example, you can use the base URI in the following
request for additional XML data:
<xsl:variable name="layout_information" select="document(concat($xml-base-uri,'/fmi/xml/FMPXMLLAYOUT.xml?
-db=products&-lay=sales&-view'))" />
Using the authenticated base URI parameter
The following parameter combines the functionality of the client-user-name and client-password parameters
with the xml-base-uri parameter:
<xsl:param name="authenticated-xml-base-uri"/>
Use this parameter to load an additional password-protected XML document that requires the same user name
and password that was specified in the original request currently being processed. For an example, see the next
section,
“Loading additional documents.”
Include this parameter statement in your XSLT stylesheet before the top <xsl:template> element.
If the values for the client-user-name and client-password parameters are not blank, then the value of the
authenticated-xml-base-uri parameter is:
http://username:password@hostname:port
If the values for the client-user-name and client-password parameters are blank, then the value of the
authenticated-xml-base-uri parameter is the same as the value of the xml-base-uri parameter.
