8.2.1 Errors at the 'Put' Step

There are two types of errors: those generic ones from the web server and those from BLAST server.

The generic web server error has no QBlastInfo section and generally contained numeric error code.

The error from BLAST server are contained in a BLAST formatting page. The latest update to BLAST URLAPI places the error message in a special section:

<div class="msg error">string</div>

Here the 'string' represents the actual error mesage. In addition, the formatting page with error will have an empty RID field under its QBlastInfo section. Some representation errors from 'Put' step are given below.
