Hi Roger
<div><br>
</div>
<div>My Cowboy app has a dependency on iBrowse - which has been working fine up until trying to start the app using “console”.</div>
<div><br>
</div>
<div><span style="font-family:Monaco;white-space:pre-wrap;background-color:rgb(255,255,255)">ibrowse:start(),</span></div>
<div>
<div style="background-color:rgb(255,255,255);font-family:Monaco;line-height:18px;white-space:pre-wrap">
<div>ibrowse:set_dest(<span style="color:rgb(163,21,21)">"<a href="http://download.geonames.org" target="_blank">download.geonames.org</a>"</span>,
<span style="color:rgb(9,136,90)">80</span>, [{max_sessions, <span style="color:rgb(9,136,90)">
10</span>}, {max_pipeline_size, <span style="color:rgb(9,136,90)">25</span>}]),</div>
<br>
</div>
</div>
<div>Then I spawn another process to fetch some files from <a href="http://genomes.org" target="_blank">
genomes.org</a> and wait for the results. The spawned process is just a wrapper around <span style="font-family:Monaco;white-space:pre-wrap;background-color:rgb(255,255,255)">ibrowse:send_req(Url, [{</span><span style="font-family:Monaco;white-space:pre-wrap;background-color:rgb(255,255,255);color:rgb(163,21,21)">"If-None-Match"</span><span style="font-family:Monaco;white-space:pre-wrap;background-color:rgb(255,255,255)">,
Etag}], get)</span> that fires off an HTTP GET request to <font face="Monaco">
Url</font> for a given <font face="Monaco">Etag</font>.</div>
<div><br>
</div>
<div>This all works fine when using the “start" parameter, but fails when using “console”…</div>
<div><br>
</div>
<div>Regards</div>

<div><br>

<div>I have a Cowboy app that at startup time, downloads various files from another web server. I’m using rebar to create a release, and this all works fine when I start the app using the “start” parameter</div>

<div>Are extra parameters needed when starting the app using “console”?</div>

</div>
<div>Not usually. What are you using to download the files from the other web server?</div>
