Method Detail

handleSitemapIndexHashed

@RequestMapping(value="/europeana-sitemap-index-hashed.xml")
public void handleSitemapIndexHashed(javax.servlet.http.HttpServletResponse response)
                                                                                           throws IOException

Generate the sitemap index file. This file groups multiple sitemap files to adhere to the 50,000 URLs / 10MB (10,485,760 bytes) sitemap limit. This index itself may not list more than 50,000 Sitemaps and must be no larger than 10MB (10,485,760 bytes). The sitemaps are split by id3hash (the first 3 letters of the record), and further split into files of maximum MAX_URLS_PER_SITEMAP if these groups exceed 50,000 URLs.

Parameters:

response - The HttpServletResponse

Throws:

IOException - For any file-related exceptions

public void handleSitemap(@RequestParam(value="from",required=true)
                                                                                 String from,
                                                                                 @RequestParam(value="to",required=true)
                                                                                 String to,
                                                                                 javax.servlet.http.HttpServletResponse response)
                                                                          throws Exception

Generate the individual sitemaps, containing the actual record IDs. Each file needs to adhere to the 50,000 URLs / 10MB (10,485,760 bytes) sitemap limit. Each sitemap is split by id3hash (the first 3 letters of the record); an id3hash may be split over multiple files if there are more than 50,000 records (the current implementation uses approx. 5.8 MB for 50,000 URLs, so the size is not the limiting factor).

Parameters:

from - start index

to - end indexw

response - The HttpServletResponse

Throws:

IOException

Exception
