            You need to send the actual file rather than just the name of the file. The server will not be able to access the file from a user's computer by its name.

            To send a file in a post request, you also need to change the content type of the request to one that Multer expects.

            integrate Open policy Agent with Knative/Kourier
            Asked 2022-Mar-19 at 20:49

            "Open Policy agent" & "Knative" each provide a tutorial for integration with "Istio". There's a lighter alternative to "Istio" : "Kourier" that requiring fewer resources.

            Is there's a way to integrate "Open Policy agent" with "Kourier" ?

            "Istio" & "Kourier" use envoy (proxy).

            I'm not sure what you're going to use OPA for here; if you're trying to constrain the types of resources which can be created, OPA + gatekeeper should work fine, though kourier only implements an internal-to-Knative interface, so you might not get as much mileage out of the integration.

            If you're trying to use OPA to govern or restrict actual HTTP requests to the workload, kourier doesn't have that capability out of the box (on purpose). You could fork it and add the functionality, but at that point it might be easier just to run Istio in non-mesh mode.

            You're setting the Select value to form.natureOfTheRequest, so you need to update that specific field on its onChange callback, rather than simply passing setForm.

            The callback could look like the following.

            I am following this guide.

            Ingress requests are getting logged. Egress traffic control is working as expected, except I am unable to log egress HTTP requests. What is missing?

            ANSWER

            Answered 2022-Feb-07 at 17:14

            AFAIK istio collects only ingress HTTP logs by default.

            In the istio documentation there is an old article (from 2018) describing how to enable egress traffic HTTP logs.

            Please keep in mind that some of the information may be outdated, however I believe this is the part that you are missing.

            T-SQL split response header from SP

            Within a T-SQL script I am calling a stored procedure, this stored procedure handles HTTP requests and is returning stuff like HTTP status code, status text and response headers.

            The stored procedure is an 3rd party managed/created SP which I cannot edit (because when the vendor is updating their application the SP will be overwritten). So I have to deal with the output of the SP.

            The response header which I am receiving after the HTTP call is made is a full string of all the headers (seperated by two spaces ' ').

            Envoy access logs format validation
            Asked 2022-Feb-02 at 20:35

            We are using envoy access logs https://www.envoyproxy.io/docs/envoy/latest/configuration/observability/access_log/usage , does envoy validate the fields that are passed to the access logs, e.g. the field format.

            I ask it from basic security reason to verify that if I use for example %REQ(:METHOD) I will get a real http method like get post etc and not something like foo. or [%START_TIME%] is in time format and I will not get something else...

            I think it's related to this envoy code

            https://github.com/envoyproxy/envoy/blob/24bfe51fc0953f47ba7547f02442254b6744bed6/source/common/access_log/access_log_impl.cc#L54

            I ask it since we are sending the data from the access logs to another system and we want to verify that the data is as its defined in the access logs and no one will change it from security perspective.

            like ip is real ip format and path is in path format and url is in url format

            ...

            ANSWER

            Answered 2022-Feb-02 at 09:54

            I'm not sure I understand the question. Envoy doesn't have to validate anything as it is generating those logs. Envoy is HTTP proxy who receives the request and does some routing/rewriting/auth/drop/.. actions based on the configuration (configured by virtualservice / destinationrule / envoyfilter if we're talking about istio). After the action it generates the log entry and fills the fields with details about original request and actions taken.

            Also there is nothing like 'real' http method. HTTP method is just a string and it can hold any value. Envoy is just the proxy who sits between client and application and passes the requests (unless you explicitly configure it i.e. drop some method).

            It depends on application who receives the method how it's treated. GET/POST/HEAD are commonly associated with standard HTTP and static pages. PUT/DELETE/PATCH are used in REST APIs. But nothing prevents you to develop application who will accept 'FOOBAR' method and runs some code over it.
