Apache rewrites the slash rule

The leading slash argument is: ignored?

What is the difference between the syntax

RewriteRule help help.php?q=noslash [L]     #1
RewriteRule /help help.php?q=withslash [L]  #2

If I hit http: // localhost / help , he goes to # 1, if I click http: // localhost // help he still refers to # 1.

Am I rightly saying that the leading slash in the first argument of the RewriteRule is essentially ignored?

Slash leading second argument: error?

Also, why does this rewrite rule not work?

RewriteRule help /help.php [L]     #1

Putting a leading slash before the second arg actually creates a 500 error for the server. Why?

I should note that I use the .htaccess file to write these rules to

I am not sure what can cause 500 errors in the second part; double-slashes may not collapse after starting the rewrite mechanism and then generate a server error.

The cause of error 500 is an infinite loop:

  • help is written in / help
  • / help is removed to help
  • help corresponded / help, etc. until the limit of MaxRewrites → 500 is reached

If a rule overwrites help, Apache is smart enough to abort rewriting at that point.
