[jira] [Commented] (JENA-2257) QueryExecHTTP#actualSendMode ignores query length causing HTTP 414
[ https://issues.apache.org/jira/browse/JENA-2257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17479412#comment-17479412 ]
Andy Seaborne commented on JENA-2257:
-------------------------------------
Hi,
Just to check some details:
How long is the query string?
Is the server the other side of any kind of reverse proxy? (it may have a shorter notion of "Request-URI Too Long").

> {_}QueryExecHTTP#actualSendMode(){_}, called in {_}QueryExecHTTP#query(String reqAcceptHeader){_}, does not consider the length of the query. In case of long queries, this causes _414 Request-URI Too Long_ errors, even if {_}sendMode=={_}{_}QuerySendMode{_}{_}.asGetWithLimitBody{_} (default):
