• Webinator 4.2 with SSL/https capability
• Tech Corner: Geographic searching
• Subscription/unsubscription and contacts

Support for SSL connections has been added to the <fetch> and <submit> functions in Vortex. This will allow users to crawl https links in addition to the standard http, as well as submit forms to secure servers.

Webinator can now crawl and index multiple protocols, including http:, https:, ftp: and more within a single crawl. Webinator 4.2 also adds the ability to perform proxy authentication for those walks requiring it.

Texis has the ability to efficiently query based on longitude and latitude. To do so you need to add an additional field to your table to hold the value created by the function in Vortex. The field needs to be a LONG.

The most common use for this field when searching is to find records which have a location near another one. The search is done using

BETWEEN (CODE1,CODE2)

  <geo2code $latitude $longitude 23000>     <!-- +/- 2.5 degrees -->
  <SQL "select Name from city where GeoCode between " $ret>
    $Name
  </SQL>
