[. . . ] The return document produced by the Web server is indexed and parsed for document links which are followed and in turn indexed and parsed. However, if the Web server does not return a page, perhaps because the URL is missing parameters which are required for processing in order to produce a page, then nothing happens. There is no page to index and parse. Example A URL without parameters is: http://server. com/cgi-bin/program? If you include parameters in the URL to be indexed, as specified with the -start option, then those parameters are processed and any resulting pages are indexed and parsed. You may list multiple domains by separating each one with a single space. Note You must have the appropriate Verity Spider licensing capability to use this option. 164 Chapter 8 Verity Spider -followdup Specifies that Verity Spider follows links within duplicate documents, although only the first instance of any duplicate documents will be indexed. You may find this option useful if you use the same home page on multiple sites. By default, only the first instance of the document is indexed, while subsequent instances are skipped. If you have different secondary documents on the different sites, using -followdup will allow you to get to them for indexing, while still indexing the common home page only once. -followsymlink Type: File system only. Specifies that Verity Spider follows symbolic links when indexing UNIX file systems. -host Syntax: -host name_1 [name_n] . . . You may list multiple hosts by separating each one with a single space. URLs not on the specified host(s) will not be downloaded or parsed. -https Type: Web crawling only. Note You must have the Verity SSL Option Pack installed to use -https. The Verity SSL Option Pack is a Verity Spider add-on available separately from a Verity salesperson. -jumps Syntax: -jumps num_jumps Type: Web crawling only. Specifies the maximum number of levels deep an indexing job can go from the starting URL. If you see extremely large numbers of documents in a collection where you do not expect them, you should consider experimenting with this option, in conjunction with the Content options, to pare down your collection. Paths and URLs Options 165 -nodocrobo Specifies ROBOT META tag directives are to be ignored. In HTML 3. 0 and earlier, robot directives could only be given as the file robots. txt under the root directory of a Web site. In HTML 4. 0, every document can have robot directives embedded in the META field. See Also -norobo and http://www. w3c. org/TR/REC-html40/html40. txt. -nofollow Syntax: -nofollow "exp" Type: Web crawling only. Specifies Verity Spider cannot follow any URLs which match the expression exp. If you do not specify a exp value for -nofollow, then Verity Spider assumes a value of "*" where no documents are followed. You can use wildcard expressions, where the asterisk ( * ) is for text strings and the question mark ( ?You should always encapsulate the exp values in double quotes to ensure they are properly interpreted. [. . . ] This metric leaves all load calculation in the hands of the probe agent. For servers that process database-intensive requests, ROUND_TRIP_TIME is not a good indication of load because ColdFusion processes the threads that calculate ROUND_TRIP_TIME differently than queued database connection requests. With this in mind, if you have a Web server that uses many concurrent connections to a database, either use AVG_REQ_TIME rather than ROUND_TRIP_TIME as your load type, or include a database call in getsimpleload. jsp to make this load type's results more indicative of actual conditions. Output variables During processing, getsimpleload. jsp generates three significant output variables that are sent in response to the probe agent's HTTP query. · CCLOADVALUE CCLOADVALUE is the load calculated by getsimpleload. jsp using one of the available load metrics. The load value identifies how busy the server is as a percentage of its total capacity. [. . . ]
