STREAM::disable¶
Description¶
Disables the stream filter for this flow.
Syntax¶
STREAM::disable
STREAM::disable¶
- Disables the stream filter for this flow or until STREAM::enable is called.
Configuration requirements:
1. This command is valid only when a Stream Profile is attached to the
virtual server. The default Stream Profile
/Common/stream
is sufficient.
2. (The following restriction is obsolete.) For TMOS versions before
and including 9.4.0, you must force BIG-IP to use chunking and
therefore remove the response content length header. This can be done
by applying a custom HTTP profile to the virtual server with Response
Chunking set to “Rechunk”. (See
SOL6422
for details.)–>
3. The stream profile can have different states (enabled vs disabled)
on each side of the connection. Calling STREAM::disable in
HTTP_REQUEST will disable the stream profile on the client-side for
HTTP requests coming in towards the server. Calling STREAM::disable in
HTTP_RESPONSE will disable the stream profile on the server-side for
HTTP responses going out towards the client.
Examples¶
See the STREAM::expression page for
additional examples.
when HTTP_REQUEST {
# Explicitly disable the stream profile for each client-side request so it doesn't stay
# enabled for subsequent HTTP requests on the same TCP connection.
STREAM::disable
}
when HTTP_RESPONSE {
# Explicitly disable the stream profile for each server-side response so it doesn't stay
# enabled for subsequent HTTP responses on the same TCP connection.
STREAM::disable
# Apply stream profile against text responses from the application
if { [HTTP::header value Content-Type] contains "text" }{
# Look for http:// and replace it with https://
STREAM::expression {@http://@https://@}
# Enable the stream profile
STREAM::enable
}
}
# This section only logs matches, and should be removed before using the rule in production.
when STREAM_MATCHED {
log local0. "Matched: [STREAM::match]"
}
If you only want to replace some http:// links with https://, you can
specify a more complex regular expression in the ‘find’ portion of the
STREAM::expression. For example, to match all http:// links except
http://schemas.microsoft.com/intellisense/ie5, you can use a negative
look behind in the regex:
http:(?!//schemas\.microsoft\.com/intellisense/ie5)
