Hi all, I've got a pair of 3400s running 9.0.5. I've created a HTTP-based VS load balancing traffic against a handful of IIS servers. I'm in a web hosting environment and I've got a situation where I need to do URL rewrites for the each customer on the BigIP. http://www.A.com/ ---> http://www.IIS_node.com/A http://www.B.com/ ---> http://www.IIS_node.com/B . . etc (there's a *significant* number of customers... at least 100) I thought of using the following iRule and I want to see if it made sense. ------------- when HTTP_REQUEST { set http_host HTTP::host switch http_host { "www.A.com" {HTTP::redirect "http://www.my_vs.com/A/"} "www.B.com" {HTTP::redirect "http://www.my_vs.com/B/"} } } ------------- Thanks - AJ

Thanks Brian and Joe. Great info! I'll give that a try and let you know how it works out. - AJ

This is a follow-on to my previous question... I did used the following iRules to do the HTTP redirect and it worked. when HTTP_REQUEST { set debug "1" set http_host [HTTP::host] if {[string equal -nocase $http_host "www.foo.com"]} {HTTP::redirect "http://192.168.1.1/foo[HTTP::uri]"; if $debug {log local0. "redirect --- http://192.168.1.1/foo[HTTP::uri]"}} } The problem is that the result is as follows: http://www.foo.com/ ---> http://192.168.1.1/foo But I really want the following: http://www.foo.com/ ---> http://www.foo.com/foo Any help or pointers would be greatly appreciated. Cheers, AJ

All you need to do is replace the 192.168.1.1 with the host name. You'll also need to put in a check for the uri to avoid an infinite loop. Ignoring what we've discussed in the previous posts, you could do the mapping you requested with this code when HTTP_REQUEST { if { [string equal -nocase [HTTP::host] "www.foo.com"] and not ([string tolower [HTTP::uri]] starts_with "/foo") } { HTTP::redirect "http://[HTTP::host]/foo[HTTP::uri]" } } I added in the "not starts with "/foo" to avoid the infinite loop. http://www.foo.com -> http://www.foo.com/foo http://www.foo.com/foo -> http://www.foo.com/foo/foo http://www.foo.com/foo/foo -> http://www.foo.com/foo/foo/foo ... -Joe

HTTP rewrite for lots of URLs

Hi all,

I've got a pair of 3400s running 9.0.5. I've created a HTTP-based VS load balancing traffic against a handful of IIS servers.

I'm in a web hosting environment and I've got a situation where I need to do URL rewrites for the each customer on the BigIP.

http://www.A.com/ ---> http://www.IIS_node.com/A

http://www.B.com/ ---> http://www.IIS_node.com/B

etc (there's a *significant* number of customers... at least 100)

I thought of using the following iRule and I want to see if it made sense.

-------------

when HTTP_REQUEST {

set http_host HTTP::host

switch http_host {

"www.A.com" {HTTP::redirect "http://www.my_vs.com/A/"}

"www.B.com" {HTTP::redirect "http://www.my_vs.com/B/"}

}

-------------

Thanks - AJ

There is also the URI::decode/URI::encode commands that will decode/encode a URI into rfc compliant form. eg: with decode, %2b will become + and with encode + will become %2b.
