[PDF_Serve]
The [PDF_Serve] tag serves a PDF file which is stored in a variable in place of the current Lasso format file. The name of the PDF file can be specified and, in supported browsers, the PDF file will be written to disk using that name and/or automatically opened in the visitor's PDF reader.
None of the contents of the current format file will be served. [PDF_Serve] completely rewrites the HTTP headers and contents of the served response. [PDF_Serve] also performs an [Abort] so no tags after [PDF_Serve] will be executed.
The first parameter to the tag should be a variable which contains the PDF file to be served. An optional -File parameter allows the name of the PDF file to be specified. An optional -Type parameter allows the MIME type of the served file (default 'application/pdf') to be overridden.

[PDF_Serve: 'PDF Data']
[PDF_Serve: 'PDF Data', -File='Example.PDF']
[Variable: 'myPDF' = (PDF_Doc: ...)]

[PDF_Serve: $myPDF, -File='Example.PDF']
[PDF_Serve: (File_Read: 'Example.PDF'), -File='Example.PDF']Examples
To serve a PDF file without writing To file:
PDF files may be served to the client browser without ever writing them to file on the local server. This is done using the [PDF_Doc] tag without the -File parameter. This allows a PDF file to be created in the system memory, but does not the save the file to a hard drive location. The resulting file can saved by the end user to a location on the end user's hard drive.
