Hi,

I'm using libcurl with Java to request some HTTPS-Pages. In order to not block the GUI, I'm runing the request in a thread.

For example:

cg = new CurlGlue();
cr = new CurlReader();
cg.setopt(CURL.OPT_WRITEFUNCTION, cr);
cg.setopt(CURL.OPT_URL, "https://xyz.de");
cg.setopt(CURL.OPT_SSL_VERIFYPEER, 0);
cg.setopt(CURL.OPT_SSL_VERIFYHOST, 0);
cg.setopt(CURL.OPT_NOSIGNAL, 1);
cg.setopt(CURL.OPT_FOLLOWLOCATION, 1);
cg.perform();
[This part a few times more]

When I run the thread for the first time, everything works ok. But when I try it a second time, the programm crashes with a external error:

Fiddler tells me, that actually the first request works ok, but the second one (the POST request) crashes.

Does anyone have any ideas how to fix this issue?

Thanks
