摘要： A system and method for receiving and validating user input for a computer resource entered into a computing system or network, and distinguishing valid and invalid portions of the user input. The invalid resource identifier, which ranges from a least specific portion to a most specific portion, is partitioned into a plurality of fields. At least one of the fields corresponding to the most specific portion of the invalid resource identifier is removed from the invalid resource identifier to create a modified resource identifier, wherein the modified resource identifier is used to attempt to access a higher level computer resource. The fields corresponding to the most specific portion of the resource identifier are removed until the modified resource identifier proves to be a valid resource identifier which can access a computer resource. The valid resource identifier is distinguished from the invalid resource identifier entered by the user, so that the user can easily determine a point at which the input is invalid.

摘要翻译： 一种用于接收和验证输入到计算系统或网络的计算机资源的用户输入以及区分用户输入的有效和无效部分的系统和方法。 从最小特定部分到最特定部分的无效资源标识符被划分为多个字段。 从无效资源标识符中删除与无效资源标识符的最具体部分相对应的字段中的至少一个，以创建修改的资源标识符，其中修改的资源标识符用于尝试访问较高级别的计算机资源。 删除对应于资源标识符的最具体部分的字段，直到修改的资源标识符被证明是可以访问计算机资源的有效资源标识符。 有效资源标识符与用户输入的无效资源标识不同，使用户可以容易地确定输入无效点。
