355 newtag396 fire,+<a+href="foobar.html">foobar</a>,+<img+src="foo.jpg"+/>
357 So this request is trying to add 3 tags to biblio #396. The CGISESSID is the same as that the browser would
358 typically communicate using cookies. If it is valid, the server will split the value of "newtag396" and
359 process the components for addition. In this case the intended tags are:
361 <a+href="foobar.html">foobar</a>
362 <img src="foo.jpg" />
364 The first tag is acceptable. The second will be scrubbed of markup, resulting in the tag "foobar".
365 The third tag is all markup, and will be rejected.
