如何移除或修改Apache服务器Server Header中的软件信息？

Hey there, let's work through this Server Header issue you're hitting. You mentioned you've already removed server signatures and know your way around .htaccess, but the server software info in the Server header is still sticking around. Here are targeted steps tailored to your shared Apache hosting setup:

1. Double-Check Your .htaccess Directives #

First off, ServerSignature Off only disables the server signature displayed at the bottom of error pages—it doesn't touch the Server HTTP header. To modify or remove that header, you need to use Apache's mod_headers module (most shared hosts enable this by default).

Add these lines before your WordPress-specific rules in .htaccess:

# Reduce Server header detail to just "Apache"
ServerTokens Prod

# Completely remove the Server header (if allowed by your host)
Header unset Server

# Optional: Replace with a custom value instead of removing
# Header always set Server "CustomServerValue"

• ServerTokens Prod strips out version numbers and extra details, leaving just "Apache" if you can't fully remove the header.
• Header unset Server attempts to eliminate the header entirely, but some hosts block this directive due to security policies.

2. Check Your Hosting Control Panel #

Many shared hosts (like cPanel, Plesk, or SiteGround's tools) have built-in settings to tweak Server headers without editing .htaccess:

• Look for sections like Apache Configuration, Security, or Advanced Settings.
• Find the "Server Tokens" option and set it to "Production" to hide version info. Some panels even let you disable the Server header outright.
• This is often more reliable than .htaccess because host-level configurations can override your file settings.

3. Address Host-Level Restrictions #

If your .htaccess changes don't take effect, it's likely due to a global Apache setting:

• Your host might have AllowOverride set to exclude FileInfo (the permission needed to use Header directives). Reach out to their support team and ask if they can either:
  • Enable FileInfo for your account, or
  • Adjust the global ServerTokens and ServerSignature settings on your behalf.
• Also, if your site uses a reverse proxy (like Cloudflare), the Server header might be coming from the proxy, not your origin server. Check your proxy's settings (e.g., Cloudflare's Network tab) for an option to remove or modify the Server header.

4. Verify Your Changes #

Don't rely on browser dev tools (they might cache old headers). Use this curl command to test directly:

curl -I https://your-wordpress-site.com

Look for the Server line in the output—you should either see it removed, replaced with your custom value, or just "Apache" with no version details.

Quick Note #

If full removal isn't possible (some hosts lock this down), using ServerTokens Prod still achieves the core goal: hiding sensitive server version info that attackers could exploit. Also, check your WordPress security plugins (like Wordfence or All In One WP Security)—many have built-in options to hide or modify the Server header with just a few clicks.
