Redirect to New Page but Pass Query String Parameters

Something like this should work:

 

 

when HTTP_REQUEST {

 

HTTP::uri [string map {".asp?" ".aspx?"} [HTTP::uri]]

 

}

 

 

This will silently replace the .asp? with .aspx? in the server-flowing URI. The client won't see this.

 

 

Or if you actually want to generate a redirect:

 

 

if { [HTTP::uri] contains ".asp?" } {

 

set uri [string map {".asp?" ".aspx?"} [HTTP::uri]]

 

HTTP::redirect "https://[HTTP::host]$uri"

 

}

 

 

Thanks for the quick response Kevin! I like the transparent method, that's even better then a redirect. We don't what the client to see anything :)

 

 

I just got an update from development that they made now want to alter the URL a little more, so now it looks like this:

 

 

https://my.domain.com/vendor/status.asp?user=xxx&password=yyy

 

to

 

https://my.domain.com/listeners/status.aspx?user=xxx&password=yyy

 

 

How does this change things?

 

 

 

Hi Brian,

You can do multiple string map and replaces at the same time.

[string map {"value1" "replacevalue1with" "value2" "replacevalue2with" }

You could look for an [HTTP::uri] that contains both vendor and asp? and do something like this:

 
when HTTP_REQUEST {
if { [HTTP::uri] contains "vendor" && [HTTP::uri] contains ".asp?" } {
set uri [string map {"vendor" "listeners" ".asp?" ".aspx?"} [HTTP::uri]]
HTTP::redirect "https://[HTTP::host]$uri"
}
}

Hope this helps.

Thanks all, I tested out each of the suggestions and it appears to be working great. One thing I wanted to do was log the original URI and the re-written URI, but I can't seem to be able to use HTTP::URI with HTTP_RESPONSE. It's probably something very simple....

 

 

when HTTP_REQUEST {

 

log local0. "OLD URI is --> [HTTP::host][HTTP::uri]"

 

HTTP::uri [string map {"vendor" "listeners" ".asp" ".ashx"} [HTTP::uri]]

 

}

 

when HTTP_RESPONSE {

 

log local0. [HTTP::URI] ??

 

}

 

 

Thanks for the help all!!

Hi Brian,

 

 

The information that you are looking for should be in the HTTP::header Location Field.

 

 

See these resource:

 

iRules Common Concepts

 

Log Http Headers

 

HTTP::header

 

 

Hope this helps.

 

Are you trying to log the updated URI value? In pre-v11.0, the HTTP::uri was cached in the same event. So you could use something like this:

 

 

when HTTP_REQUEST {

 

log local0. "Rewriting [HTTP::uri] to [string map {"vendor" "listeners" ".asp" ".ashx"} [HTTP::uri]]"

 

HTTP::uri [string map {"vendor" "listeners" ".asp" ".ashx"} [HTTP::uri]]

 

}

Thanks Aaron, that is exactly what I was looking for. Michael, I tried looking at the HTTP::header location field and I wasn't seeing the new URL in the location field, not sure if I had it correct.

 

 

I have another wrinkle with this implementation...we currently have an iRule that is looking at the old URIs and directing the traffic to a different pool based on the URI value. I have added the re-write code to the existing iRule and it seems to work, however, the string tolower funtion doesn't appear to be working:

 

 

when HTTP_REQUEST {

 

switch -glob [string tolower [HTTP::uri]] {

 

"/client/order.asp*" -

 

"/vendor/status.asp*" -

 

"/xml/order.asp*" -

 

"/xml/status.asp*" {

 

log local0. "Rewriting [HTTP::uri] to [string map {"Vendor" "Listeners" ".asp?" ".ashx?"} [HTTP::uri]]"

 

HTTP::uri [string map {"Vendor" "Listeners" ".asp?" ".ashx?"} [HTTP::uri]]

 

pool beta.res-direct.com_B2B_HTTP

 

}

 

 

We basically want to remove any case sensitivity on the URI.

 

 

Thanks so much for your help, this forum loaded with awesome folks.

Can you try string map -nocase to do a case insensitive replacement?

 

 

log local0. "Rewriting [HTTP::uri] to [string map -nocase {"Vendor" "Listeners" ".asp?" ".ashx?"} [HTTP::uri]]"

 

HTTP::uri [string map -nocase {"Vendor" "Listeners" ".asp?" ".ashx?"} [HTTP::uri]]

 

 

Aaron

Working like a charm, thanks so much again all for the help. I really appreciate it!

Actually, I have another wrinkle to add...here's the code we're using and what is happening. Also note I had to replace the " " with {} per a configsync issue (http://support.f5.com/kb/en-us/solutions/public/12000/700/sol12795.html)

 

 

when HTTP_REQUEST {

 

switch -glob [string tolower [HTTP::uri]] {

 

"/client/order.asp*" -

 

"/vendorABC/status.asp*" -

 

"/vendorXYZ/status.asp*" {

 

log local0. "Rewriting [HTTP::uri] to [string map -nocase {{VendorABC} {Listeners} {status.asp?} {abcstatus.ashx?}} [HTTP::uri]]"

 

HTTP::uri [string map -nocase {{VendorABC} {Listeners} {status.asp?} {abcstatus.ashx?}} [HTTP::uri]]

 

log local0. "Rewriting [HTTP::uri] to [string map -nocase {{VendorXYZ} {Listeners} {status.asp?} {xyzstatus.ashx?}} [HTTP::uri]]"

 

HTTP::uri [string map -nocase {{VendorXYZ} {Listeners} {status.asp?} {xyzstatus.ashx?}} [HTTP::uri]]

 

pool beta.res-direct.com_B2B_HTTP

 

}

 

 

So when a post hits /VendorABC/status.asp?... it gets routed correctly to /Listeners/abcstatus.ashx?...

 

But

 

The next post to /VendorXYZ/status.asp?... it gets an error becuase it's hitting /Listeners/abcstatus.ashx?... instead of /Listeners/xyzstatus.ashx?....

 

 

Because the asp page is named the same in both URIs, the first rule is detecting it and sending it to the wrong location. Is there a way to say when both /VendorABC/status.asp? are in the URI, direct to /Listeners/abcstatus.ashx? and when /VendorXYZ/status.asp? are in the URI, direct to /Listeners/xyzstatus.ashx?

 

 

I'm pulling my hair out with this one....Thanks in advance!
