How do I get Apache's RewriteRule, Location, and PerlHander to work nicely together?...

I now want to implement a RewriteRule -- a la a "cool" linked data URL -- to redirect URLs with a specific shape to SemanticWeb.pm, and I use the following:

 RewriteRule ^/etexts/id/(.*) /sandbox/semantic-web.cgi?id=$1

In other words, all request starting with /etexts/id should be redirected (rewritten) to go to semantic-web.cgi. Unfortunately, all requests go directly to the touched file and not to my Perl package; the Location directive seems by-passed....


Resolved. Alas, I needed to add [passthrough] to my RewriteRule configuration:

RewriteRule ^/etexts/id/(.*) /sandbox/semantic-web.cgi?id=$1 [passthrough]

From the mod_rewrite documentation:

  * 'passthrough|PT' (pass through to next handler)

  This flag forces the rewrite engine to set the uri field of the
  internal request_rec structure to the value of the filename
  field. This flag is just a hack to enable post-processing of the
  output of RewriteRule directives, using Alias, ScriptAlias,
  Redirect, and other directives from various URI-to-filename
  translators. For example, to rewrite /abc to /def using
  mod_rewrite, and then /def to /ghi using mod_alias:

    RewriteRule ^/abc(.*) /def$1 [PT]
    Alias /def /ghi

  If you omit the PT flag, mod_rewrite will rewrite uri=/abc/... to
  filename=/def/... as a full API-compliant URI-to-filename
  translator should do. Then mod_alias will try to do a
  URI-to-filename transition, which will fail. Note: You must use
  this flag if you want to mix directives from different modules
  which allow URL-to-filename translators. The typical example is
  the use of mod_alias and mod_rewrite.

I sincerely apologize for wasting people's time and bandwidth.
