Well now where stands the X-Try here for (more host caches)
And the X-Try-Ultrapeers: stands for the the acces to real servers ??

Am i right ???

The second question is about the first header that returned
FP-Auth-Challenge: 5DPC77G53LGOPHKNPPXI3TZSHUXT3IDS
Do i have to replay on this with a MD5 .... something:confused:

The third question (wow)
On some hostcaches i connect and get disconnect before i can even send a header.
Some hosts do that (am i dooing some thing wrong here ???)

Well tnx guyz
