I can't find your mail in the archive.

I think you can do this in tsung. For example, if you have a csv with 2 
columns, url + expected response, you can:

<?xml version="1.0"?>
<tsung dumptraffic="protocol">


   <option name="file_server" id="urls" value="urls.csv" ></option>

   <session name="http_csv" probability="100" type="ts_http">

  <repeat name="myloop" >
    <setdynvars sourcetype="file" fileid="urls" delimiter=";" order="iter">
      <var name="url" />
      <var name="response" />

   <if var="myurl" neq="end">
    <request subst="true">
       <match do="log" when="nomatch" subst='true'>%%_response%%</match>
       <http url="%%_url%%" version='1.1' method='GET' />

  <!--  the last line of the file should be "end"-->
  <until var="url" eq="end"/> </repeat>

you can also include erlang code inside the tsung configuration file, see 
for example:
