Cirrus
Cirrusredirect to to 301 location
We are trying to come up with an irule that will:
redirect based on id value X (eg. 144 string) to a new URL and append the same value in this new URL . So it must extract the id=X value and append it to the redirect URL
Example:
https://value-same.domain.com/external/services/datastorage/#/?id=144"
Must be redirected (301 location)
https://different-website.domain/external/services/datastorage/#/?id=144"
the value 144 could be any value. I was thinking of this
I have tried a range of irules usind data groups but it has to get the value from the request
Does anybody have a suggestions? My irule below did not match anything but thats because of not hostname etc.
when HTTP_REQUEST {
if { [HTTP::uri] contains "/external/services/datastorage/#/?id=144"" }{
HTTP::respond 301 Location "https://different-website.domain/external/services/datastorage/#/?id=144""
}
}
My bad, there's a typo.

Hello, I've notciced your URL is build with a reserved character "#" , you might want to review this because hash character is used as a delimiter to separate the URI from a fragment identifier, so everything after /#/ in your query will not be sent to the server unless JavaScript code running inside the browser. If client doesn't send it of course it will also not be matched by BIGIP HTTP profile so recalling it with [HTTP::uri] for an exact match comparison will fail.
Other than this, matching content is pretty simple, if you have an HTTP profile attached to your VS you can use [HTTP::query] or [HTTP::uri] to recall information from client request.
Depending on how many matches you have on ID, you can use if/switch/datagroups to build your syntax ; this is a sample with a switch statement
when HTTP_REQUEST { if { [HTTP::uri] starts_with "/external/services/datastorage/" }{ set id [findstr [HTTP::query] "id=" 3 &] switch -glob $id { 143 - 144 { HTTP::respond 301 Location "https://different-website.domain[HTTP::uri]" } 145 { log local0. "this is a different match" } default {} } # in above switch statement , ?id=143 or ?=id 144 will match same condition ; ?id=145 will match its own condition ; every other ?id=xxx value will match default } }
southern_shreddThanks for the response, could we make it such that anything after /datastorage/XXXX be extracted and appended to the new URL? So it does not have to be numeric values only (144,145 etc.
Example
/#/?id=144https://different-website.domain/external/services/datastorage/#/?id=144
https://different-website.domain/external/services/datastorage/#/50b2580d-9f9f-41b7-b0af-618d570de14f/receipt
https://different-website.domain/external/services/datastorage/#/?vi=BYR&saksnr=12221&id=144
redirected to:
https://different-website.domain/external/services/datastorage/#/?id=144
https://different-website.domain/external/services/datastorage/#/50b2580d-9f9f-41b7-b0af-618d570de14f/receipt
https://different-website.domain/external/services/datastorage/#/?vi=BYR&saksnr=12221&id=144So perhaps using "HTTP::query" & /path maybe
when HTTP_REQUEST {
if { [HTTP::uri] starts_with "/external/services/datastorage"- CA_Valli
It didn't have to be numeric, script captured everything that followed "id=" so "id=abCD456" could be a match as well. I used numeric in my test because I assumed it was.
Code for scripting a wildcard match is much simpler, but once again I'm concerned that all of your URLs have a fragment identifier, which (being a client-only feature) I believe is not being sent by browser -- therefore parser will not see that part with [HTTP::uri] or [HTTP::query].

I got an error when trying to compile the irule
error: [command is not valid in the current scope][}]
