public static java.lang.String truncate(java.lang.String contentType)

Truncate passed mimetype. Ensure no spaces. Strip encoding. Truncation required by ARC files.

Truncate at delimiters [;, ]. Truncate multi-part content type header at ';'. Apache httpclient collapses values of multiple instances of the header into one comma-separated value,therefore truncated at ','. Current ia_tools that work with arc files expect 5-column space-separated meta-lines, therefore truncate at ' '.

Parameters:

contentType - Raw content-type.

Returns:

Computed content-type made from passed content-type after running it through a set of rules.
