[OpenSIPS-Users] openxcap: 64k limit for query results?

Hi Greg,

As Wget needs to know the size of  data in
advance maybe your JSP page asks corresponding to its buffer size.

Use InputStreamReader when constructing BufferReader in your JSP page.

Hi Saúl,

The OpenXCAP server in question is an active production machine for other services, so I'm a little hesitant to make changes to the hostfile for testing. :)

I did do an ngrep on the local machine and retry the query, and I do see it returning 64k of data:

HTTP/1.1 200 OK..Content-Length: 65535..Accept-Ranges: bytes..Server: OpenXCAP/2.0.0..ETag: "564e6f706fbf147ee1d7b27668470a81"..Date
>  : Tue, 23 Oct 2012 09:01:50 GMT..Content-Type: application/resource-lists+xml....[..]

I've also read that wget can't handle chunked data (although this response doesn't seem to be chunked), so I've tried curl, with similar results:

* Connected to [host.domain] (xx.xx.xx.xx) port 9000 (#0)
>* Server auth using Basic with user '[username at host.domain]'
>> GET /xcap-root/resource-lists/users/[username at host.domain]/index HTTP/1.1
>> Authorization: Basic [..]
>> User-Agent: curl/7.18.0 (i486-pc-linux-gnu) libcurl/7.18.0 OpenSSL/0.9.8g zlib/ libidn/1.1
>> Host: [host.domain]:9000
>> Accept: */*
>< HTTP/1.1 200 OK
>< Content-Length: 65535
>< Accept-Ranges: bytes
>< Server: OpenXCAP/2.0.0
>< ETag: "[..]"
>< Date: Tue, 23 Oct 2012 09:07:22 GMT
>< Content-Type: application/resource-lists+xml

We may end up implementing a workaround to obtain this specific data via another route, but if you have any other ideas, I'd be happy to give them a try in case anyone else runs into a similar problem.
