URLRewriter错误，在网上搜了半天都找不到答案，大家帮我看看

Question

郁闷，这个问题一直困扰着我。楼上的兄弟，就是URL重写呀。没有代码的，只是配置一下而已。难道大家都没有用过URL重写吗？

Answer 1

楼上兄弟，我看了。确实没有判断是否为NULL的。该如何解决？难道可以去掉吗？ protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
{
// log information to the Trace object.
app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter"); // get the configuration rules
RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules; // iterate through each rule...
for(int i = 0; i < rules.Count; i++)
{
// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$"; // Create a regex (note that IgnoreCase is set...)
Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // See if a match is found
if (re.IsMatch(requestedPath))
{
// match found - do any replacement needed
string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo)); // log rewriting information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl); // Rewrite the URL
RewriterUtils.RewriteUrl(app.Context, sendToUrl);
break; // exit the for loop
}
} // Log information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Exiting ModuleRewriter");
}

有人说是因为缓存失效引起的。请问大家，如何不让缓存失效？在web.config里面可以配置吗？

Answer 3

根本就不用自己写程序，把微软那个下载下来，应用一下，再调整一下WEB.CONFIG就可以用了

Answer 5

<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" />

Answer 6

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<configSections>
<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter"/>
</configSections>
<connectionStrings>这个有用嘛？

这样看不出问题，如果不是自己写的url重写dll，用别人的话，错误很常见
