The `downloadtypes` array is a comma-separated list of file extensions and has a default value of: `xls,doc,pdf,txt,csv,zip,docx,xlsx,rar,gzip`. **Defining `downloadtypes`** The `downloadtypes` config parameter allows you to define what file extensions will be considered a download. For example, if you want to track the downloading of `bin` and `que` files, you can do this by adding the downloadtypes config parameter with a value of `bin`,`que`. **Using downloadtypes** Suppose the `downloadtypes` config parameter contains: "`xls`,`doc`" Page contains the following hyperlink: `<a href="smartsource.xls?lang=en">SmartSource Spreadsheet</a>` Clicking the link generates the following parameters: `DCS.dcssip=tagbuilder.webtrends.com` `DCS.dcsuri=/Help/EventTracking/smartsource.xls` `DCS.dcsqry=?lang=en` `WT.ti=Download:SmartSource Spreadsheet` `WT.dl=20` **JavaScript Example:** ``` window.webtrendsAsyncInit = function () { var dcs = new Webtrends.dcs(); dcs.init( { dcsid: "dcs12345610000wocrvqy1nqm_123p", download : true, downloadtypes : "xls,doc,pdf,txt,csv,zip,docx,xlsx,rar,gzip", }); dcs.track(); } ``` JavaScript Reference: | dcsMultiTrack Parameter | Value | | --- | --- | | **DCS.dcssip** | hostname | | **DCS.dcsuri** | pathname or "/" | | **DCS.dcsqry** | search (if present) | | **WT.ti** | "Download:" + title | | **WT.dl** | 20 | | **WT.nv** | Enclosing element id or classname (if present) |
