# HTML Processing with WKOOP

The `WKOOPHtmlExtraction` task processes an HTML file that is associated with a document. It extracts links and metadata and adds these to the document in a metadata field named `HTML_PROCESSING`. The task appends a page to the document content that contains the plain text extracted from the HTML source. It also sets the field `AUTN_NO_FILTER`, to prevent the document being processed by KeyView.

This section describes how to configure HTML processing with WKOOP.

You can configure WKOOP HTML extraction as a pre-import task (`Pre0` in the following example). The `Pre0` parameter also specifies the name of a section that contains the settings for the task. In the following example the section is named `HtmlProcessingSettings`.

    [ImportTasks]
    Pre0=WKOOPHtmlExtraction:HtmlProcessingSettings

    [HtmlProcessingSettings]
    WKOOPPath=F:\IDOL\WebConnector\WKOOP.exe
    ProxyHost=proxy.domain.com
    ProxyPort=8080
    SSLMethod=NEGOTIATE
    ExtractLinks=TRUE
    ResolveLinks=TRUE
    Url=https://www.example.com/

The `WKOOPPath` parameter specifies the path to WKOOP. WKOOP is not included with CFS, so you must install the IDOL Web Connector and specify the path to the WKOOP executable file. You must install a version of WKOOP that is the same as, or later than, the version of CFS that you are using.

If you are running CFS on a machine that is behind a proxy server, set the `ProxyHost` and `ProxyPort` parameters to specify the proxy server to use to access the web. The `SSLMethod` parameter specifies the version of SSL or TLS to use when connecting to the web site, and is necessary to retrieve resources over HTTPS. Setting this parameter to `NEGOTIATE` uses the latest version that is supported by both CFS and the web server.

The `ExtractLinks` parameter accepts a Boolean value that specifies whether to extract links from HTML pages and add the links to the document metadata. When `ResolveLinks=TRUE` the links are resolved so that indexed documents contain absolute URLs. The `Url` parameter specifies the source URL so that links can be resolved. You do not need to specify the exact URL of the page being processed, as long as all URLs in the document being processed are relative to the web server.

For a full list of configuration parameters that you can use to configure WKOOP HTML extraction, refer to the Connector Framework Server Reference.
