addResponseHeader

Syntax

addResponseHeader(field, value)

Parameters

field

value

Description

For example, if the response you send to the client uses a custom content type, you should encode this content type in the response header. The JavaScript runtime engine automatically adds the default content type (text/html) to the response header. If you want a custom header, you must first remove the old default content type from the header and then add the new one. If your response uses royalairways-format as a custom content type, you would specify it this way:

deleteResponseHeader("content-type");
addResponseHeader("content-type","royalairways-format");

Remember that the header is sent with the first part of the response. Therefore, you should call these functions early in the script on each page. In particular, you should ensure that the response header is set before any of these happen:

• The runtime engine generates 64KB of content for the HTML page (it automatically flushes the output buffer at this point).
• You call the flush function to clear the output buffer.
• You call the redirect function to change client requests.

blob (path)

path

// Create a cursor
cursor = database.cursor("SELECT * FROM customer WHERE
   customer.ID = " + request.customerID

// Position the pointer on the row
cursor.next()

// Assign the blob data
cursor.photo = blob("c:/customer/photos/myphoto.gif")
cursor.office = blob("c:/customer/photos/myoffice.gif")

// And update the row
cursor.updateRow("employee")
