Abstract

List of preferences that affect networking behavior.
Description of acceptable values and behavior.
Audience

QA testers, developers and "power users" with extensive networking internals experience.
For general technical documentation on preferences (including how to edit them), see "A Brief Guide to Mozilla Preferences"

The goal is to accurately document Core-Necko behavior and Firefox 3 UI.
Overview

The sections are in roughly alphabetical + functional order. The preferences are in order of usage by the UI (which is not often alphabetical order). Relevant bugs are provided only when absolutely necessary.

Note: Do not change any of these via about:config unless you know what you are doing. If you are uncertain what that phrase means, you probably do not.

If you qualify, you are probably one or more of the following:

    You have a feature-spec or code-level understanding of the preference.
    You are doing testing and have a clear performance metric.
    You are doing this in conjunction with a packet trace to monitor Necko's changed behavior.

checkloaduri will disable file:// URLs on pages from a network (http: https: ftp:) source, for security reasons.
Errors are sent to the javascript console, not to the user via dialog box. This preference only works in Gecko versions before 1.8 (so Firefox 1.0 and Mozilla Suite builds). In Firefox 1.5 and Seamonkey 1.0 this preference no longer has an effect.

그동안 다루지 안았던 부분에 대해서만 몇자 적어 봅니다.

위 내용중에  browser.cache.disk.max_entry_size와 browser.cache.memory.max_entry_size에 관한것 입니다.

일전에 browser.cache.disk.max_entry_size의 값은 0으로 설정하였지요.

이 부분이 그동한 다루지 않았던 내용이 browser.cache.memory.max_entry_size입니다.

기본값은 위에서 보는 거와 같이 5120인데 이 값을 -1로 설정하는 겁니다.

주석 부분에  no limit 이라고 설명하고 있읍니다.

왜 이값을 -1로 설정하냐면 요즘은 메모리가 8G이상 설치하여 쓰시는 분이 많을 거라 봅니다.

메모리에다 기록합니다. 사용량이 증가 하기 때문에 설치된 메모리가 작다면 -1로 하지 마세요.

기본값을 쓰거나, 이니면 적당한 크기를 지정하세요. 단위는 Kb입니다.
