In an apache conf file, if a line is start with #, that line is counted as comment. For example,
#This is a comment line
#And then the following is some real settings:
AllowOverride None
However, this is not allowed.
#And then the following is some real settings:
AllowOverride None #A comment that starts in the middle of line
Is it possible to starts a comment in the middle of the line? And if yes, how?
回答1:
The documentation states that it is not possible:
... Lines that begin with the hash character "#" are considered comments, and are ignored. Comments may not be included on the same line as a configuration directive ...
回答2:
I believe only # is parsed as there is no real need for it. But if you really need you can use IfDefine block, which will be ignored unless a matching variable has a definition.
<IfDefine myexisterenceIsForJustAComment>
...
</IfDefine>
Look at discussion at : https://bugzilla.redhat.com/show_bug.cgi?id=1349546
Not sure if these are supported in latest versions (< httpd-2.2.15-53) but you can try below which was supported in earlier versions. You may be in luck if you are on older version.
In earlier/older versions of Apache, I remember it was okay to include a comment at the end of a line (wrapped in double quotation marks), like so:
<Limit GET >
Order Allow,Deny
Allow from all
Deny from xxx.xxx.xxx "# I am in inline comment"
</Limit>

Apache interprets its conf files line by line. And it considers a line starting with # as a blank line (or line break) and skips the line.
Also it doesn't have a symbol to indicate comments because conf files have many special symbols, which might let them to disable middle-line comment.
