How can I configure Apache to always return an error

  • 772

I want to deliberately throw an arbitrary error. Something appropriate between the <LocationMatch>...</LocationMatch> directorives. e.g.:

<LocationMatch "^/myurl/.+">
    ThrowError 503
</LocationMatch>

<LocationMatch "^/anotherurl/.+">
    ThrowError 504
</LocationMatch>

<LocationMatch "^/safeurl/">
    # not throwing an error from this path
    Options +Indexes
</LocationMatch>

What can I use instead of ThrowError 503? I want to force the server to tell the user whatever error code I choose (e.g. 404, 403, 501, etc) as a means of testing my rules. Worst case I'd like a message written to the error_log if I cannot actually throw an error at the browser.

I'm aware I could possibly use mod_rewrite to perform a RewriteRule .* - [R=503,L] however I want to just use the core modules (I do not have mod_rewrite compiled into my Apache).

Update: have discovered I can say RedirectMatch 410 . which will report a "Gone" message to the user as one potential solution.

    As you mentioned yourself, the Redirect directive (not necesssary for RedirectMatch, I think?) which is part of mod_alias should do the trick.

    From the docs:

    Other status codes can be returned by giving the numeric status code as the value of status. If the status is between 300 and 399, the URL argument must be present, otherwise it must be omitted. Note that the status must be known to the Apache code (see the function send_error_response in http_protocol.c).

    Example: Redirect 303 /three http://example.com/other

    Edit:

    I don't know much about C code, but from a quick look at http_protocol.c, these are your options:

    100 Continue
    101 Switching Protocols
    102 Processing

    200 OK
