Replace multiple strings with iRule?

Hi there,

 

I've got an occasion to replace a few strings in an HTTP_RESPONSE. I can't seem to figure out the syntax. I've got it replacing one using STREAM::expression but I'm not sure how to do two or three distinct texts.

 

Thanks for any advice...

    I believe the 

    STREAM::expression
    page provides the answer you're seeking:

    Specifically, you can space-delimit replacement pairs, as in:

    when HTTP_REQUEST {
    STREAM::disable
    HTTP::header remove "Accept-Encoding"
}

when HTTP_RESPONSE {
    STREAM::expression {/onething/anotherthing/ /secondthing/yetanother/}
    STREAM::enable
}

    Thanks. Sorry for wasting your time. I should have read the specs on STREAM::expression
