Syntax for http header manipulation

Hi,

 

 

I’m testing http header manipulation. I’m trying to figure out the syntax of table 13.15 of the LTM Config Guide. I have the following functioning iRule:

 

 

when HTTP_REQUEST {

 

set URI [HTTP::uri]

 

if { $URI starts_with "/foo.html" } {

 

log local0.warn "URI starts with foo.html"

 

HTTP::header replace host foo.gwrf5.com

 

HTTP::uri "/foobar.html"

 

use pool foo

 

}

 

}

 

 

 

Is there some reason I can’t set the HTTP::host header in the same fashion as the HTTP::uri? When I try the rule as follows:

 

 

when HTTP_REQUEST {

 

set URI [HTTP::uri]

 

if { $URI starts_with "/foo.html" } {

 

log local0.warn "URI starts with foo.html"

 

HTTP::host “foo.gwrf5.com”

 

HTTP::uri "/foobar.html"

 

use pool foo

 

}

 

}

 

 

I get the following syntax error when saving the rule:

 

01070151:3: Rule [rewrite] error:

 

line 5: [wrong args] [HTTP::host "foo.gwrf5.com"

 

 

Also, when I try the rule as follows:

 

 

when HTTP_REQUEST {

 

set URI [HTTP::uri]

 

if { $URI starts_with "/foo.html" } {

 

log local0.warn "URI starts with foo"

 

HTTP::header host foo.gwrf5.com

 

HTTP::uri "/foobar.html"

 

use pool foo

 

}

 

}

 

 

It saves fine, but I get the following runtime error:

 

 

May 27 01:22:08 tmm tmm[4286]: 01220001:3: TCL error: Rule rewrite - Illegal argument. Illegal argument. Illegal argument. Illegal argument. Ille (line 1) invoked from within "HTTP::header host foo.gwrf5.com"

 

 

Seems to me like both of these other rules should work according to the documentation. I didn't want to dump this to support until I knew for sure what I was doing.

 

 

Thanks,
