PageReadHeaderHTTP (Function)

In french: PageLitEntêteHTTP

Reads and returns one or more HTTP headers received by the current page (these headers are sent by the client to the server in the current request).

Example

sReferer is string = PageReadHeaderHTTP("Referer")

// Example for retrieving all incoming HTTP headers
// Browse the incoming HTTP headers
nHeaderSubscript is int
sAHeader is string
sAllHeaders is string

LOOP
// Next header
nHeaderSubscript ++
sAHeader = PageReadHeaderHTTP(nHeaderSubscript)
// Header read?
IF sAHeader = "" THEN BREAK // no other header
sAllHeaders += [CR] + sAHeader
END
Info(sAllHeaders)

Syntax

Reading a header identified by its name Hide the details

<Result> = PageReadHeaderHTTP(<Header to read>)

<Result>: Character string

Header value.
Empty string ("") if the header is not found.

<Header to read>: Character string with quotes

Name of header to read.

Reading a header identified by its subscript Hide the details

<Result> = PageReadHeaderHTTP(<Subscript>)

<Result>: Character string

Header value. The header name is returned in uppercase characters and the dashes are replaced by "underscore" characters (the initial name of HTTP header as it was sent by the client is not available).
Empty string ("") if there is no header to read.

Remarks

In a dynamic site, the headers are the HTTP headers received when connecting to the site.
To list all the headers, use the syntax by subscript until the function returns an empty string.
