Thinking Outside the Box: Rewriting Web Pages with F5 Distributed Cloud (XC)
This article demonstrates how to dynamically rewrite web page content, such as updating links or replacing text, by using native features in F5 Distributed Cloud (XC). It provides a creative workaround that leverages JavaScript injection to modify pages on the fly, avoiding the need for a separate proxy like NGINX or BIG-IP.iRule or Re-write Profile
I'm trying to work out how to do the following. I have an irule that is directing source traffic (based on IP) to a specific pool I have a rewrite policy > changing https://example.com to https://example.com/text this is all working The problem I have, is I'd like https://example.com to stay the same in the client's browser But after the client connects to the backend servers, they return a uri https://host1.com I'd like that to appear as https://example.com I looked at my rewrite policy and was thinking I could do a response This doesn't appear to work. Should I be using a single iRule to Replace the name (inbound) Direct to a pool Replace the name (outbound)
How to rewrite a path to a backend service dropping the prefix and passing the remaining path?
Hello, I am not sure whether my posting is appropriate in this area, so please delete it if there is a violation of posting rules... This must be a common task, but I cannot figure out how to do the following fanout rewrite in our nginx ingress: http://abcccc.com/httpbin/anything -> /anything (the httpbin backend service) When I create the following ingress with a path of '/' and send the query, I receive a proper response. curl -I -k http://abczzz.com/anything apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: mikie-ingress namespace: mikie spec: ingressClassName: nginx rules: - host: abczzz.com http: paths: - path: / pathType: Prefix backend: service: name: httpbin-service port: number: 8999 What I really need is to be able to redirect to different services off of this single host, so I changed the ingress to the following, but the query always fails with a 404. Basically, I want the /httpbin to disappear and pass the path onto the backend service, httpbin. curl -I -k http://abczzz.com/httpbin/anything apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: mikie-ingress namespace: mikie annotations: nginx.ingress.kubernetes.io/rewrite-target: /$2 spec: ingressClassName: nginx rules: - host: abczzz.com http: paths: - path: /httpbin(/|$)(.*) pathType: Prefix backend: service: name: httpbin-service port: number: 8999 Thank you for your time and interest, Mike
Rewrite http:// to https:// in response content
Problem this snippet solves: (Maybe I missed it, but) I didn't see a code share for using a STREAM profile to rewrite content from http to https. This share is just to make it easier to find a simple iRule to replace http:// links in page content to https://. It's taken directly from the STREAM::expression Wiki page. How to use this snippet: You'll need to assign a STREAM profile to you virtual server in order for this to work (just create an empty stream profile and assign it). Code : # Example which replaces http:// with https:// in response content # Prevents server compression in responses when HTTP_REQUEST { # Disable the stream filter for all requests STREAM::disable # LTM does not uncompress response content, so if the server has compression enabled # and it cannot be disabled on the server, we can prevent the server from # sending a compressed response by removing the compression offerings from the client HTTP::header remove "Accept-Encoding" } when HTTP_RESPONSE { # Check if response type is text if {[HTTP::header value Content-Type] contains "text"}{ # Replace http:// with https:// STREAM::expression {@http://@https://@} # Enable the stream filter for this response only STREAM::enable } } Tested this on version: 11.5
Conditionally inject text into HTML responses
Hello, An LTM needs to inspect a server's response pages and rewrite the HTML so that, for every URL written without a specific URI path, the URI path is inserted. Example: Server sends back calls to URL http://server.example /path /image.jpeg -- Ok, no action Server sends back calls to URL http://server.example/image.jpeg -- Need to inject /path I haven't been able to get a working syntax, any help will be immensely appreciated.
