IE user agent

Hi!

 

i have an app that support only IE. i want to display a some message to all browsers except IE. i have found that only IE have a user agent string that contains "Trident". how to write an irule that redirect any except user agent that contains "Trident"?

 

Thanks,

 

Aviv Hassidim

 

I have this irule that open a message page only to user agents that contains some string:

 

when RULE_INIT { set static::refresh_time 15 set static::notification_page {

 

System Notification

You are using an unsupported browser and will be redirected to Myspace.com

 

Wait $static::refresh_time seconds to continue, or click

 

} } when HTTP_REQUEST { switch -glob [ string tolower [HTTP::header User-Agent]] { "msie 10.0" - "msie 9.0" - "msie 8.0" - "msie 7.0" - "msie 6." { HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" log local0. "Client IP:[IP::client_addr] has been redirected with user agent :[HTTP::header User-Agent]" } default { go to a default location if nothing matches } } }

    Change this part:

     

    "switch -glob [ string tolower [HTTP::header User-Agent]] { "msie 10.0" - "msie 9.0" - "msie 8.0" - "msie 7.0" - "msie 6." {"

     

    to

     

    if { !([string tolower [HTTP::header User-Agent]] contains "trident") } {

    Ok! Now is works. This Irule will search for trident is the http request and if there is no such a string it will show an html page with a message that not ie browser is not supported. enjoy!

    when RULE_INIT { set static::refresh_time 30 set static::notification_page {

    BODY {text-align: center}

    <h3>Open This Site Only in IE</h3>
