Subject [jira] [Commented] (NUTCH-1317) Max content length by MIME-type
Date Wed, 25 Sep 2013 20:08:05 GMT

    [ https://issues.apache.org/jira/browse/NUTCH-1317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13778013#comment-13778013

Sebastian Nagel commented on NUTCH-1317:
----------------------------------------

Thanks, [~cguzel]! Patch looks possible (not tested yet). Two notes:
* instead of overriding the limit for each MIME type by its own property (e.g. {{http.content.limit.vnd.ms-excel}}),
a simple map file similar to {{adaptive-mimetypes.txt}} seems more extensible (and more efficient
because no String operations are done to look-up the max. length for a MIME type)
* code to determine max. length for given MIME type is doubled in patch: could be "centralized"
in HttpBase (plugin lib-http) which is inherited by protocol-http and httpclient

> The good old http.content.length directive is not sufficient in large internet crawls.
For example, a 5MB PDF file may be parsed without issues but a 5MB HTML file may time out.
