You can use # to comment out individual lines. Is there a syntax for commenting out entire blocks?

I've tired surrounding the block (specifically a <Directory> block) with <IfModule asdfasdf>...</IfModule>, but that didn't work.

I came across this post from a Google search for "Apache block comment". Later, I discovered a non-perl, non-import solution from Apache's core documentation (although I'm sure this is very non-intended practice). From the core documentation for Apache 2.0, you can see that the tag <IfDefine> will handily ignore statements when the parameter you specify does not exist:

<IfDefine IgnoreBlockComment>

So that'll successfully "comment" out the statements in between.

I am not sure if apache has such type of comments.

As a workaround, you can use include statement in the following way:



When you want to comment this block, you just need to comment out the include line:

#include yourfile.conf

Sad :( I've heard NGinx has better easier configuration. – ripper234 Jan 2 '12 at 10:39
Comments aren't configuration. A good text editor will allow you to quickly add stuff to multiple lines, too. In Textmate, it's Option+Drag. – ceejayoz Jan 2 '12 at 18:57

AFAIK, Apache doesn't support this.

But, if you're using vim, here's a tip (from my co-worker) to comment out a Apache config block.

For instance, given this snippet:

<Directory "a/b/c">
    SetEnvIf X-Forwarded-For ^x\.y\.z\.t let_me_in
    Order allow,deny
    allow from env=let_me_in
    ErrorDocument 403

Put the cursor under the D character at the opening <Directory ...> line and type the following:

V/Dir -> Enter

followed by:

:s/^/#/ -> Enter

  • V - to highlight the current line
  • /Dir - selects the whole block
  • :s/^/#/ - puts a # at the begin of each line

I think it's easier to just go in Visual Block mode on the opening tag, scroll down to the closing tag, and then do shift-I (big i) # Esc. – Janus Troelsen Apr 16 '13 at 20:41
