Events after HTTP_REQUEST

I think that's a bug.

Yes, that's a bug.

Here, try this rule:

 
 when LB_SELECTED { 
    set server_addr [LB::server addr] 
 } 
 when HTTP_REQUEST_SEND { 
    if { $server_addr ne "" } { 
       clientside { HTTP::header replace Host $server_addr } 
    } 
 } 
 

Hmm. No fun. Would it be possible to get around it by putting the iRule into bigip.conf directly?

This rule should work:

 
 rule test_rule { 
    when HTTP_REQUEST_SEND { 
       clientside { HTTP::header replace Host [IP::server_addr] } 
    } 
 } 
 

Cool, well, both variations of the rules work, but don't get me the desired behavior with SiteMinder...maybe because the host name is not getting changed between the BigIP and the backend, only from the client the the BigIP? (I assume that's what the "clientside" does).

 

 

Thanks for everyone's help here, I appreciate it.

Huh!?

 

 

Both Dr. Teeth and I tested that the Host: header is changed on server-side of connection (I verified via tcpdump on the server that the Host: header contained the IP of the target node).

 

 

The "clientside" simply mean evaluate the command in the braces on the clientside context, which is where the headers are available.

 

 

Perhaps, SiteMinder requires the hostname to be a name and not IP address? This would be a bit trickier to do, but could be done with a data group/class mapping table.

What triggers the HTTP_CLASS_SELECTED event? -Brian

Is HTTP_CLASS_SELECTED a valid event? I get an error when I try to put it in a rule.

 

 

Also, in the following doc: http://devcentral.f5.com/Default.aspx?tabid=29&articleType=ArticleView&articleId=27 [URL]http://devcentral.f5.com/Default.aspx?tabid=29&articleType=ArticleView&articleId=27 [/URL] is "SERVER_SELECTED" supposed to be "LB_SELECTED"?

 

 

Thanks,

Also what is SERVER_LINE? -Brian

What triggers the HTTP_CLASS_SELECTED event?This is a new event in 9.2 that gets triggered when an httpclass profile matches (the profile is also new).

 

is "SERVER_SELECTED" supposed to be "LB_SELECTED"?YUP!

 

Also what is SERVER_LINE?It's an old event that never made prime-time. It is part of a profile called the line profile which simply parses traffic for CR/LF and fires the CLIENT_LINE or SERVER_LINE events as lines are parsed. We never ended up publishing the line profile. Hopefully it will be there someday...
