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.
Rewrite profile
Hello guys, So as proxypass will be soon removed I am creating rewrite profile as substitute. However it is not working 😞 so this is my scenario (just sample) will be redirected to Configuration Rule Type: Both Client: /home/ Server: http://www.f5.com/ My proxypass configuration for Data group was www.cathy.com/home := www.f5.com/ HTTP_F5_pool My rewrite profile is not working but my proxypass is working. I think the difference is on the pool? Can anyone check my config. Am I missing something? Thank you!
Switch option always matches on default
Hello everybody. I have one question which probably for some people should be something simple, but I have spent a few days on a lab environment and studying a lot, with no succesfull results. I need to do a previous check to send a path which starts with /pf to a pool, but always goes to the default pool. The first or second part is working, but I can't make it work together. This is the iRule: when HTTP_REQUEST { if {[string tolower [HTTP::uri]] starts_with "/pf" } { HTTP::uri [string map {"/pf/" "/PF/"} [HTTP::uri]] pool Pool_apache_lab } switch -glob [string tolower [HTTP::path]] { "default" { HTTP::respond 200 content { Default switch } } } } Mandatory is not to touch "switch -global", but for the first match, I can use a "global", "if", "else if" or anything you suggest. Thanks in advance.
URI Rewrite not rewriting form action
We have a rewrite profile (of type URI Translation) that doesn't seem to be rewriting what we want it to. I looked at the HTML that it should be rewriting, it seems to be called via a form action: Could the hex encoding of the URI be causing it not to fire? It's looking for https://server1.contoso.com:8203/sap/ but it might only be seeing it with hex encoding of the special characters https&x3a;&x2f;&x2f;server1.contoso.com&x3a;8203&x2f;sap&x2f; Rewrite rules should work with form actions, correct? I think I have the basics right, response settings has rewrite headers and rewrite content both checked, in the virtual server under Content Rewrite the rewrite profile is set, and the HTML profile is set to HTML - I don't know what else it could be. We're on the following build: BIG-IP 11.6.0 Build 0.0.401 Final Thanks!
