  • 1.  Reading the incoming headers in xslt and pass it to dp:url-open

    Posted Mon October 07, 2024 07:58 PM

    Hi All,

    I have a requirement to pass the all incoming headers(we don't know which headers client is sending) to dp:url-open in xslt/

    I have tried to read the incoming header names using the service variable(var://service/header-mainfest) as below.

    <xsl:variable name="IncomingHeaders" select="dp:variable('var://service/header-mainfest')"/>

    <xsl:variable name="IncomingHeaderswithValues">

    <xsl:for-each select=$IncomingHeaders/headers/header">

    <xsl:variable name="headername" select="@name"/>

    <xsl:variable name="headervalue" select="dp:http-request-header('headername')"/>

    <header name="$headername"> <xsl:value-of select="$headervalue"/> </header>

    </xsl:for-each>

    </xsl:variable>

    but i'm unable to get the header values, do we have any other way to read the incoming headers dynamically. Thanks in advance!

    Why do you have to use url-open? Every DataPower service would automatically pass the incoming headers to its configured backend. 
    If you have to, have a look at dp:get-metadata()

    Ibm remove preview
    dp:get-metadata()
    Fetches metadata for the current transaction.

    Hi Bhargav,
    Your statement

    <xsl:variable name="headervalue" select="dp:http-request-header('headername')"/>

    is setting variable headervalue to the request header named by the string literal 'headername' which probably doesn't exist.  I believe you meant to use the headername variable value as the name of the header you want to get the value

    <xsl:variable name="headervalue" select="dp:http-request-header($headername)"/>

    Best Regards,

    Steve Linn
