Subject [jira] [Commented] (HTTPCLIENT-1075) ContentEncodingHttpClient.execute(HttpGet, ResponseHandler<T>) throws IOException when reading chunked gzip response
Date Wed, 13 Apr 2011 15:04:05 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13019367#comment-13019367
] 

James Abley commented on HTTPCLIENT-1075:
-----------------------------------------

Oleg,

I suggest editing the name of this issue to be "ContentEncodingHttpClient.execute(HttpGet,
ResponseHandler<T>) throws IOException when reading compressed response" to make it
clearer what the underlying issue was? It affected both deflate and gzip responses, and the
fix handles both cases. Chunking had no bearing on the bug as far as I can tell.

Thanks,

James

Creating a JIRA per the recommendation of Oleg from httpclient-users.
