I see that you do:
if (mimeTypes != null) {
String mimeType =
HttpUtils.getMimeTypeFromContentType(contentType);
if (!mimeTypes.contains(mimeType)) {
throw new AbortedFetchException(url, "Invalid
mime-type: " + mimeType, AbortedFetchReason.INVALID_MIMETYPE);
}
}
my question is then: what is it done at the caller side with the
handling of AbortedFetchException handling the httpclient?
Nothing. The finally {} block for where that exception is thrown calls
safeAbort with the HttpGet object, and that in turn calls
request.abort().

As I mentioned in the previous post, i'm using httpclient for a
webcrawler i'm writing. at the moment i'm doing something like this:
while(toVisit.size() > 0){
client.execute(method);
String mime = getContentType(method); // which
does method.getResponseHeader("Content-Type").getValue();
if(supportedMimes.contains(mime){
handle(method.getResponseBody());
} else {
continue;
}
}
the problem is that i can see that the crawler hangs up a lot of
time
processing urls that are going to be ignored. so i guess it's
downloading the whole stream before ignoring it. is there a way i
can
download just the header, check the content type and only then
download
the stream (at the time of getResponseBody())?
See the code I'd previously referenced for an example of exactly
that.

Make sure you abort the request if you skip getting the response.
