Hi, We are seeing an issue with Gzip not happening consistently with one of our websites. We have enabled static compression on the IIS.

The content encoding appears inconsistently say 4 out of 10 times if I hit the website URL. Can you please let me know why this behavior is seen?

    Hi @Pratik Vaidya ,

    Please check your IIS Compression module, make sure that dynamic content and static content all enabled.

    If you enable failed request tracing to check compression, you will find that static compression won't work when a static file didnot get hit frequently.

    If you rely this request doezens times, the header will appear.

    Another thing, there's a limit for minimum file size for compression. You can modify that value according to your application.
