[AOLSERVER] ns_register_filter problem

[Ross Simpson]

Hello,

I'm trying to use ns_register_filter, and am running into difficulties.

I have the following code in an init.tcl:

  ns_register_filter postauth GET  /*/bob mqa.processHostedRequest
  ns_register_filter postauth POST /*/bob mqa.processHostedRequest

mqa.processHostedRequest looks like this:

proc mqa.processHostedRequest {trash} {
    if [catch {
        ns_return 200 text/html [ns_adp_parse -file /path/to/common.adp]
    } err] {
        mqa.logError "mqa.processHostedRequest: '$err'"
    }
    return filter_break
}


I would like common.adp to be parsed and returned, and then for the
connection to be closed -- no attempt should be made to actually load
'bob', since it doesn't exist.

This is only half-working.  The parsing is happing and I'm seeing the
output, but afterward, I get a second set of headers:

  HTTP/1.0 404 Not Found
  MIME-Version: 1.0
  Date: Fri, 14 Feb 2003 21:31:46 GMT
  Server: AOLserver/3.5.5
  Content-Type: text/html
  Content-Length: 21499
  Connection: close
  Content-Type: text/html
  Content-Length: 547

Notice the two sets of Content-Type and Content-Length headers.. strange.

Does anyone have any idea what's going on here?
I could see getting a 404 if aolserver was trying to load the requested page, since it 
doesn't exist.
>From the docs (ns_register_filter, postauth section:

  * TCL_BREAK (using: return "filter_break"): The server will not
    process any more post-authorization filters for this connection,
    and it will run the function registered to handle this request.

Thoughts? Ideas?

thanks
Ross
