My company uses Apigee Edge Public Cloud and we have some target servers hosted in Azure via "Front Door". The clients that call our Apigee proxies are getting intermittent '502 - Unexpected EOF' failures. Apigee support has said its because Front Do...

We use a sharedFlow within the "post-proxy flowhook". The last time we had to make a change, it did not go well because when the sharedFlow was deployed to the "production" environment, one message processor did not deploy it successfully. We updated...

We have a target server defined so that it enables MTLS by following Apigee's documentation here: https://docs.apigee.com/api-platform/system-administration/configuring-ssl-edge-backend-service#define-tstore-validation.Within that section, it says "I...

I have a similar problem as this issue from 2019 (https://www.googlecloudcommunity.com/gc/Apigee/Lookup-Cache-not-working-when-I-cache-the-data-using-Response/m-p/12214#M8225) but the responses on that thread are not showing a solution.We have proxy ...

A backend api team asked me to create a proxy to their service on aws and to secure the backend connection with mutual TLS. I noticed right away, they have not configured TLS correctly. They used a certificate issued to other backend services we have...

Alright - I have some updates!1. I deleted the cert chain and confirmed the connection starts to fail with TLS error. 2. I uploaded ONLY the expired 'leaf' certificate, and confirmed this also fails with a TLS error.3. I deleted the expired 'leaf' an...

Right.. just to be sure we're thinking the same thing:The "root" and "intermediate" certs are not loaded as different 'aliases' in the trustStore. When I created the alias for this "host.example.com", I uploaded one file that contains the entire chai...

Here is a sequence diagram to help clarify: When Apigee initiates the connection to the backend (step 20) the server "host.example.com" will present it's certificate (step 30). Apigee should be checking that this certificate is trusted by looking for...

Ok. I was under the impression that "responseCache" was effectively the same as doing PopulateCache/LookupCache policies but just a simplified way to define them.Based on your reply, it sounds like we could replace the "ResponseCache" policies with "...

Hi Krishna, I expect your endpoint like `/shops/{shopId}/orders/{orderId}` should be defined as a Flow in either the proxy or target definition, so then what I'd do is log apigee variable "current.flow.name" with each request. Then all requests to th...
