網(wǎng)絡(luò)技術(shù)是從1990年代中期發(fā)展起來的新技術(shù),它把互聯(lián)網(wǎng)上分散的資源融為有機整體,實現(xiàn)資源的全面共享和有機協(xié)作,使人們能夠透明地使用資源的整體能力并按需獲取信息。資源包括高性能計算機、存儲資源、數(shù)據(jù)資源、信息資源、知識資源、專家資源、大型數(shù)據(jù)庫、網(wǎng)絡(luò)、傳感器等。 當(dāng)前的互聯(lián)網(wǎng)只限于信息共享,網(wǎng)絡(luò)則被認(rèn)為是互聯(lián)網(wǎng)發(fā)展的第三階段。 HTTP協(xié)議狀態(tài)碼的含義表-1 HTTP協(xié)議狀態(tài)碼的含義 號 碼 | 含 義 | 100 | Continue | 101 | Witching Protocols | 200 | OK | 201 | Created | 202 | Accepted | 203 | Non-Authoritative Information | 204 | No Content | 205 | Reset Content | 206 | Partial Content | 300 | Multiple Choices | 301 | Moved Permanently | 302 | Found | 303 | See Other | 304 | Not Modified | 305 | Use Proxy | 307 | Temporary Redirect | 400 | Bad Request | 401 | Unauthorized | 402 | Payment Required | 403 | Forbidden | 404 | Not Found | 405 | Method Not Allowed | 406 | Not Acceptable | 407 | Proxy Authentication Required | 408 | Request Time-out |

網(wǎng)絡(luò)的神奇作用吸引著越來越多的用戶加入其中,正因如此,網(wǎng)絡(luò)的承受能力也面臨著越來越嚴(yán)峻的考驗―從硬件上、軟件上、所用標(biāo)準(zhǔn)上......,各項技術(shù)都需要適時應(yīng)勢,對應(yīng)發(fā)展,這正是網(wǎng)絡(luò)迅速走向進步的催化劑。
