构建一个Web站点时,不仅应当提供较强的数据库访问功能,还应为站点建立一种安全机制,充分保证数据的安全性。要为站点建立一种安全机制,当然可以用程序开发语言来完成,但这要求站点开发者有较高的程序编写能力,一般人不易实现。而利用Dreamweaver MX 2004提供的功能,再加上少量的编码,也可构建网站的安全机制。掌握这项技术,对于程序开发能力较弱的人员.在一定程度上也能保证自己站点的安全。 相似文献

Apache中的站点默认允许所有的客户端都可以访问,如果要对Web站点的客户端进行控制,需要设置目录访问控制。目录访问控制只针对某个目录进行授权访问,可通过IP地址和域名、用户身份认证方式来实现对客户端的访问控制。 相似文献

传统的网站只是在页面上使用计数器进行简单的访问者数量的统计。随着网站运营规模的扩大,依靠这种简单的数量统计并不能真正对网站运营状况做以全面的评估,难以为网站运营提供有意义的参考;基于Web的网站访问流量统计系统在功能上强化了对用户行为的统计和分析,有利于网站管理者、开发者根据目标客户使用网站的实际情况制定网站经营战略,调整网站运营架构,进而对网站整体进行更有意义的改进。 相似文献

Prior studies have suggested that a good Website design which facilitates a user’s Web browsing behaviour would generally lead to better user performance. In this research, we examine user Website behaviour as a way to understand Website design using a “think aloud” protocol analysis. Main theoretical contributions of this research are the illustration of the flow of cognitive processes during the Website browsing and the establishment of Website design dimensions – the meaning and content implied by Website content, its outward form, and the structure and navigation – in relation to user performance. 相似文献

The objective of this study was to combine internationalization and localization of Websites and improvement of Website usability with user-centred design methods. This study designed for internationalization and localization of Websites for Asian users, and implemented usability engineering into every phase of Website usability testing, based on the internationalization and localization perspectives of the honeywell.com/your home Website. The first step was to develop the usage scenarios. Three Asian usability specialists carried out one heuristic evaluation session for the current honeywell.com/your home Website. The usability problems were analysed and possible solutions to these problems were discussed. In the next phase, cluster analysis was utilized to test current information architecture. The results provided options for future information architecture development for this Website. Finally, a performance measurement test was conducted to investigate the performance for Asian users. Based on the results, suggestions for improving the Website usability from the localization perspective were provided. The results demonstrate the user-centred design (UCD) approach and stress international and local issues in Website development to Website designers. 相似文献

不法分子通过Tor等匿名通信系统构建暗网隐匿其不法行为,给网络监管带来了严峻挑战。网站指纹识别技术能根据加密流量来推测用户访问的站点,是一种有效的监管手段。已有的网站指纹识别技术采用的多为基于批处理的静态模型,无法有效解决概念漂移问题。针对Tor网站指纹,文章提出一种基于自适应随机森林(ARF)算法的动态网站指纹识别模型。模型使用自适应随机森林算法作为分类器,支持手工特征以及自动特征两种输入,能够根据特征流动态更新分类器模型,实现网站指纹的在线分类识别。实验结果表明,基于ARF的动态网站指纹识别模型检测能力优于已有的多种网站指纹识别方法,并能够有效解决已有模型存在的概念漂移问题。 相似文献

The Internet is used by an ever-increasing number of people worldwide. However, there is little understanding of the interaction between Internet technology and the behavior of different human personality types. This article focuses on the impact of the need for closure on the desired level of interactivity of a given Website. For this experiment, four commercialized Websites were created: (1) flat—with no hyperlinks and no time pressure; (2) flat with time pressure; (3) interactive with no time pressure; and (4) interactive with time pressure. All of the Websites contained identical information presented in different ways. The interaction between need for closure as a personality variable and as a situational variable and level of interactivity of the Website as a variable on consumer behavior was examined. A 2 (high need for closure vs. low need for closure)×2 (time pressure vs. no time pressure)×2 (interactive vs. non-interactive Website) between-subjects design was used. One hundred and eighty-two experienced Web surfers took part in the experiment, and were randomly assigned to one of the Websites. After surfing they completed a questionnaire about their level of satisfaction with the Website, their willingness to purchase the product offered there, and their wish to return to the Website. It was predicted that people with a high need for closure would prefer a Website with fewer hyperlinks, while people with a low need for closure would prefer a Website containing more hyperlinks. Results confirmed our predictions with regard to the conditions without time pressure. In contrast, when participants were under time pressure, the results were completely reversed: People with a low need for closure preferred the flat Website and those with a high need for closure preferred an interactive Website. The implications of the results on Website design are discussed. 相似文献
