-------------------------------------
Summary: Optionally disable remote HTTP connections when resolving
XML entities
Key: ANY23-504
URL: https://issues.apache.org/jira/browse/ANY23-504
Project: Apache Any23
Issue Type: Improvement
Reporter: Sebastian Nagel
The Any23 parser should optionally avoid to open HTTP connections when parsing
XML.
While testing the Nutch's Any23 plugin with 2.5 (NUTCH-2892) on the file
"BBC_News_Scotland.htm", the parser did hang for about two minutes with an open
HTTP connection to "hans-moleman.w3.org" and the following stack:
