IDOL 24.1.0

# Web Connector

## 24.1.0

### New Features

- The view action can be configured to return an image, thumbnail image, or PDF of a web page. This provides a preview of the page that reflects its appearance when it was last synchronized. (Normally, the view action returns the HTML source of the page at the time of the request). This feature ensures that the preview returned by the view action matches the data in your IDOL index. It can also result in a better preview because rendering HTML returned from the view action might not work well if a page requires external resources such as stylesheets and scripts. For more information about this feature, refer to the documentation for the new configuration parameter `ViewRenditionFormat`.

### Resolved Issues

- The connector could terminate unexpectedly when `UseSitemapFromRobots=TRUE` and the `robots.txt` file pointed to a sitemap that was an index of other sitemaps.

## 23.4.0

### New Features

- The configuration parameter `MaxLinkPercentagePerPage` has been added, so that you can more easily prevent the connector from ingesting index and navigation pages. This parameter specifies the maximum percentage of textual content on a page that can be represented by links, before the connector does not ingest the page. Pages that exceed the maximum percentage are still crawled and the connector follows the links that it finds.

### Resolved Issues

There were no resolved issues in this release.

## 23.3.0

### New Features

- The configuration parameters `SitemapIndexUrlCantHaveRegex` and `SitemapIndexUrlMustHaveRegex` have been added, so that you can choose the sitemaps to process when you configure the connector to process a sitemap index (which is a list of sitemaps).

- The `View` action returns document metadata. To obtain the metadata set the action parameter `NoACI=FALSE`, because by default the `View` action returns the binary content of the file.

### Resolved Issues

- Crash dumps for the embedded web browser (WKOOP) were written to disk even though this behavior was disabled. The connector is designed in such a way that WKOOP can terminate without adversely affecting the connector.
- The connector did not handle cookies correctly (all cookies were treated as if their name and value were empty).

## 23.2.0

### New Features

- Web Connector can use the Mozilla readability library to clip pages. Clipping removes uninteresting parts of a page such as navigation bars and advertisements, to prevent irrelevant information being added to the IDOL index. Automatic clipping was available in previous versions of Web Connector but the readability library produces better results in some cases. To clip pages using the readability library, set `ClippingMode=READABILITY`. This feature is not available on FIPS-compliant platforms.
- When extracting metadata from a page, Web Connector can write the information into structured document fields. Earlier versions of Web Connector could not be configured to write this information into sub-fields.
- The connector has a new configuration parameter, `FormSubmissionType`, which specifies whether the connector should expect page navigation to occur when a form is submitted. If the connector does not observe the specified behavior, the page is not processed and is retried during the next synchronize cycle.
- To improve performance, the connector stores downloaded robot protocol data in a cache. The configuration parameters `RobotProtolEnableCache` (default `TRUE`) and `RobotProtocolCacheDirectory` have been added so that you can configure this feature.
- The configuration parameter `CookieStoreDirectory` has been added, so that you can choose where cookies are stored.
- The connector includes an example configuration for retrieving data from Google News.

### Resolved Issues

- When processing a site map with a large number of entries, Web Connector could queue ingest-delete commands for web pages that still existed.
- UTF-8 multibyte whitespace was not handled correctly when the configuration parameter `NormalizeWhitespace` was `TRUE`.
- The connector could incorrectly remove whitespace between some words when the configuration parameter `NormalizeWhitespace` was `TRUE`.
- There was an issue with the Web Connector 12.13 zip package for Linux x86-64 (an incorrect version of `libstdc++.so.6` was included). When installed from this package, the embedded web browser (WKOOP) did not start.

### Notes

- As a result of the improvements to clipping, you must update any task configurations that include clipping. The `Clipped` parameter has been removed and replaced with a new parameter, `ClippingMode`. For more information about clipping in Web Connector 23.2, please refer to the Web Connector Help.

- As a result of the improvements to metadata extraction, you must update any task configurations that extract metadata.

  - In earlier versions of Web Connector, the `MetadataSelector` and `MetadataFieldName` parameters accepted multiple values. With Web Connector 23.2 these parameters accept a single value and you should use the new parameter `MetadataFieldSections` to specify the names of sections that contain these parameters (one section for each field that you want to create in your IDOL documents).

    The configuration parameter `MetadataSelectorExtractPlainText` has been renamed to `MetadataExtractPlainText`.

    For example:

    Web Connector 12.13 | Web Connector 23.2
    --- | ---
        [MyTask]
        ...
        MetadataSelector0=h1
        MetadataFieldName0=HeadingOne
        MetadataSelectorExtractPlainText=TRUE
        [MyTask]
        ...
        MetadataFieldSections0=ExtractH1

        [ExtractH1]
        MetadataSelector=h1
        MetadataFieldName=HeadingOne
        MetadataExtractPlainText=TRUE

  - The configuration parameters `ChildMetadataSelector`, `ChildMetadataSelectorExtractPlainText`, `ChildMetadataFieldName`, and `ChildMetadataAttribute` have been removed. You can now extract metadata for child documents using the same parameters that you would use for the main document. Use the new parameter `ChildDocumentMetadataFieldSections` to specify the names of sections that contain settings for metadata extraction from child documents.
