如何防止elmah url /elmah.axd在使用akamai时不被缓存

Question

So, for one of our ASP.NET MVC website, we are using Akamai to cache all pages, what has happened coz of this, even our elmah url "/elmah.axd" is also cached.

A quick google search didnt yield any help, as of now I have a workaround to see the actual elmah logs, I apply a random query param and I can get to see the non-cached errors.

How do akamai to not cache it ?

Answer 1

I'm gonna answer your question, hoping that your elmah.axd is under heavy authentication :)

you can setup an akamai delivery configuration to avoid caching any resource you decide, you can specify a rule on the property manager where you can match by path or extension or whatever other combination/condition and apply a no-store behaviour, this will basically bypass the cache for every hit and akamai will just proxy the client's call to your servers, still effectively hiding the origin but actually querying it every time

PS. if i were you i would completely close-off the elmah script using akamai (creating a rule that will just redirect or bounce any requests to it) and access only calling the origin (which should be known only to a handful of people)

PPS. a good practice tip: don't allow random query strings to create new cache-keys and bypass akamai's cache, you are making your origin server potentially vulnerable to flood, rendering the nice akamai shield less effective
