Configuration of Netscape and Internet Explorer
(Historic browsers of the original syllabus — the configuration concepts are identical in today's Chrome/Edge/Firefox.)
1. Why Configure a Browser?
Configuration tailors the browser to the user's network, security, privacy and performance needs: proxy settings, cache size, home pages, security zones, cookie policies, helper applications.
2. Netscape Navigator Configuration
Accessed via Edit → Preferences (on the Menu bar).
| Category | Settings |
|---|---|
| Appearance | Show toolbars, fonts, colours, default home page |
| Navigator | Home page URL, history expiry (days), languages accepted |
| Mail & Newsgroups | Mail server (POP/IMAP + SMTP server names), identity (name, e-mail address), signatures |
| Advanced | Enable Java, JavaScript, stylesheets, cache (memory/disk size, location, clear buttons), proxies (direct / manual / automatic proxy config URL), smart browsing |
| Privacy & Security | Certificates (personal, web-site), cookie manager (accept all / only original site / disable), form autofill, password manager |
Typical proxy setup (Manual): HTTP Proxy = proxy.college.edu, Port = 8080, "Use same proxy for all protocols", Exceptions/No-proxy list = *.college.edu, localhost.
3. Internet Explorer Configuration
Accessed via Tools → Internet Options (six tabs).
| Tab | Settings |
|---|---|
| General | Home page(s), browsing history (delete cookies/files/history), Settings for Temporary Internet Files — disk space and folder, accessibility |
| Security | Four zones — Internet, Local intranet, Trusted sites, Restricted sites; per-zone security level (High/Medium/Low) for ActiveX, Java, scripts, downloads |
| Privacy | Cookie policy slider (Block All → Accept All), per-site cookie exceptions, pop-up blocker |
| Content | Content Advisor (ratings), certificates, auto-complete, feeds |
| Connections | Dial-up/VPN setup, LAN Settings — auto-detect, automatic configuration script, proxy server address/port and exceptions |
| Advanced | HTTP 1.1, security (SSL/TLS versions), multimedia (play sounds/videos), accessibility options |
IE LAN proxy example: check "Use a proxy server", Address proxy.company.com, Port 8080, Bypass for local addresses.
4. Common Configuration Concepts (any browser)
- Home page / start-up pages — page(s) opened at launch.
- Proxy server — routes requests through a caching/filtering intermediary (direct, manual, or PAC script).
- Cache management — memory/disk cache size and clear policy; trade-off between speed and freshness.
- Security zones / site permissions — trust levels for scripts, ActiveX, downloads, camera/mic.
- Cookies & privacy — accept/block/third-party rules; "do not track".
- Helper applications / plug-ins — handlers for PDF, media, Office documents.
- Languages & encoding, fonts, accessibility (text size, high contrast).
- Downloads — default folder, ask-every-time, malware scanning.
5. Netscape vs IE Configuration — Comparison
| Aspect | Netscape Navigator | Internet Explorer |
|---|---|---|
| Config UI | Edit → Preferences (tree, one panel) | Tools → Internet Options (six tabs) |
| Security model | Certificate + cookie manager, single policy | Security zones per site category |
| Proxy | Manual or automatic (PAC URL) | LAN settings: auto-detect / script / manual |
| Cache | Memory + disk cache settings | Temporary Internet Files (disk space, folder) |
| Extensibility | Plug-ins, Java, JavaScript | ActiveX controls, add-ons |
| Mail client | Bundled (Messenger) | Bundled (Outlook Express) |
