Parameter “base64encode” means that corresponding content (variable or result of function) will be converted to base64. Base64 is a way to encode the data with using of ASCII-characters like A-Z, a-z, 0-9 and some special characters like ”+” and ”/”.

It can be useful to encode binary data or some param to send it somewhere (for example, to add some data in URL).

NOTE: By default the resulting content will be parsed (all <#..> tags will be evaluated) before to apply this filter. You can control this behavior throught the parameter AnalyzeTagParams

<#MyVar setValue="12345">
<#MyVar base64encode="1">
