      observation nap: usually like the network, for many netizens confused 200 0 64 status code also to read. &NBSP
     First, let's analyze the composition of 200 0 64 status codes:
0 64:sc-status (protocol State) Sc-substatus (Protocol sub State) Sc-win32-status (Win32 status code)
      sc-status (protocol status): 200 connection succeeded
  Sc-win32-status ( Win32 status Code): 64 The specified network name is no longer available
      first, 200 states, we all know that only the browser issued a request to receive the full request, it will be 200 states, This proves that this request is not a program or a network error. &NBSP
      Secondly, as for the reasons for the 64, first of all to think: The search engine crawler has snapshots, the server normal impact generated and recorded 200 states, Search engine according to their own criteria to determine whether the page needs to update the snapshot, and then, when the current data does not need to be downloaded, the active disconnect with the server this conversation, when the server will be labeled 64 status (You know, 64 represents the specified network name is no longer available).
      iis log analysis is as follows:
      For example, new station ITSOBSERVE.COM  Baidu Spider as long as encountered with the directory under the index.html is 200 0 64 status, but almost all of the pages are 200 0 0 state, so we can determine the emergence of 200 0 64 Another reason is that the new station is still in the examination period, temporarily not included. As for the old station that is the reason for analysis. No original content site article title front several pages are the same, Baidu is certainly not included.
       from this we can see the Baidu spider included a general process of the page.
       Spiders First step on this new station by link or otherwise, analyze page content especially title, no matter home pageOr inside the spider will first be based on the weight of the domain name to determine whether to collect or update the snapshot, if the weight is low will return to 0  64 status, for the internal page Focus analysis title, if the spider Library has many similar pages to return 200 0 64 states, such as the original is the revenue SAC or update the snapshot.
       so through the above analysis, as well as my views and analysis of other users and my own server log analysis, Baidu Spider appeared 200 0 64 status code is very normal. Now come to the conclusion, and personally feel that this conclusion will be the final version. &NBSP
      If you want to solve this problem, it is to update the content or increase the chain, especially the original content.
