• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Andrey Kosyakov]

The numbers displayed in Size column of Network panel are wrong for cached resources:
- Size should be the actual size of cached resource (currently 0)
- Transfer Size should be the size of response headers (currently 0)

didReceiveResponse should not special-case cached resources. It would be better to call didReceiveContentLength for cached resources instead.

This would go away.

> Source/WebCore/inspector/front-end/Resource.js:241
> +        var size = this.cached || this.revalidated ? 0 : Number(this.resourceSize || this.responseHeaders["Content-Length"] || 0);

Could you replace ternary operators with guards for ease of understanding?

> Source/WebCore/inspector/front-end/Resource.js:309
> +    get revalidated()

get statusIsNotModified?

Removed additional resource size parameter to didReceiveResponse, issue additional call to didReceiveContentLength in case we got 304 and had a cached resource.

In what cases do we use Content-Length header Is it more accurate? Was is used for gzip?
