Why iis

HttpRuntime creates a collection of HttpApplication objects. The page starts and is loaded when the request has completed the HTTP route. IIS server is very popular, and its use is widespread. It offers a range of useful features and is an effective tool for many IT administrators. Overall, IIS is a versatile and highly configurable web server. It can do far more than host ASP. NET applications, if you extend it. By extending it, you can create a stable, flexible, and effective Windows IIS server.

Whether you install IIS on Windows 7, 8, or 10, the setup process is the same. This includes PowerShell 2. You can click the plus sign beside each feature to expand it, drilling deeper to access application development features, for example. This is a simple setup process, and you can do it all from within your basic Windows 10 environment. To do this, take the following steps:.

Most servers will use port 80 to manage HTTP traffic, but you can change this if you think another port might be more suitable to your needs.

Changing the port through which your HTTP traffic goes is easy. Change this to the port of your choice. If you want to do this on Windows 8 or Windows 8. Understanding how to access and take advantage of log files is an important part of maintaining an IIS server. Log files are useful because they keep track of all the activities in your server.

By loading log files, you gain visibility into whatever actions you specify. You can filter the log files by time and date, the amount of transmitted data, or the related IP address. Typically, accessing your log files is straightforward. You should then see your website on the left side. Select it and click on the logging icon. The first part remains the same, up until you run IIS. IIS is mostly used for creating websites and applications, but you can also use it to create virtual directories.

In IIS, specific names—chosen by you—are mapped to directories. The name gives users a quick way of accessing server-hosted content, whether in the form of another website, or via media like videos and pictures.

With IIS 6, apps and virtual directories were treated as distinct and separate components. From IIS 7 onward, apps and virtual directories exist in a hierarchy, which means a single site can contain numerous apps and multiple virtual directories.

Any business hoping to survive should always be considering how its security measures fare against the countless threats out there. One of these threats is unauthorized access. This keeps external parties and entities from gaining inappropriate access to your information, as they would need permission to do so.

This begins with creating a certificate. To do this, make sure Windows Server is installed, then install and configure IIS according to the instructions in this guide. You can also attribute a certificate to a website. Finish the Certificate Wizard process and go to the Properties page.

From here you can define the name, the. NET version, the managed pipeline mode, and whether you want the application pool to start instantly or not. Understanding the part application pool users have to play is important. IIS will create a virtual user for each application pool. Virtual users have folders associated with them.

Remember if you delete an application pool, the user folders will still exist. To save a little space, you can go ahead and delete these. Every 29 hours, application pools recycle. They also recycle whenever the configuration file changes. However, you can tweak how often the application pools recycle to suit your preferences. The recycling process frees up memory being consumed by apps running in the pool and is a great way of keeping runaway processes from eating up your server memory.

But what uses up memory? Anything on the stack and heap, basically. This means static variables, static properties, items in the memory cache, object-to-object referencing, chunks of memory waiting to be disposed of, and much more. You can also define specific times by ticking the box and entering an hour into the field—for example, 8 p.

The recycling settings also let you determine memory-based maximums, like virtual memory usage and private memory usage. In addition, you can alter settings for how recycling events are logged.

Event log entries are generated when an application pool is recycled, according to your specifications. You can define which events call for a log to be generated. If you access the advanced settings, then you can do plenty more. For example, whenever the recycling process is initiated, a new process starts.

This new process will have a new PID, but you can change this via the advanced settings if you like. You can alter pretty much any of the recycling configurations from this dialog box.

Perhaps you have exclusively used Apache in the past and are looking for a change. Moreover, what seems like an argument of IIS vs. Apache often tips into the common Microsoft vs.

Linux debate. There are a lot of mixed messages out there, so hopefully this guide will afford you a more objective view. This is an open-source server created by the Apache Software Foundation. Bugs are resolved within the community, often in a highly collaborative fashion, and updates are frequent. A big benefit of Apache is that you can run it on any major operating system.

This is a comprehensive web server solution. Apache usage takes up a substantial chunk of the web server solution market, though its prevalence has been in decline since IIS has increased in popularity. Apache is a very versatile tool. It also has a range of authentication modules, including:. Despite its impressive suite of features, there are some issues with Apache. The main one is feature bloat. Many applications fall victim to this fault, which basically means they have a huge quantity of features that go mostly unused.

This is quite a shocking figure, especially considering there are often complaints of Apache not being an especially speedy application. Remember, sc-bytes represents the size of the file sent from the server back to the client. We would likely all agree that the time-taken for the requests exceeds a 'normal' response time. However, the size of the files is something which the administrator or developer would need to analyze to determine if the sizes are within an acceptable range.

The conclusion is that the GetDetailsView. You may want to look at the date and time when problems where occurring for this file, and examine the code in the file with any issues that occurred. For example, the IIS logs contain a list of variables that were passed in the query string; you could check those values for bad data. The examples provided in figures 4 - 8 help gain an understanding around where the root cause of an issue may exist.

It is likely, however, that this analysis has only rendered a better view of the situation which will lead to more questions and deeper analysis. If that's the case you may want to create a representation of this data in a more presentable manner. The following section covers this in detail. Screenshots of a command window containing LogParser queries and their results may be fine during the analysis phase of a performance problem; however, if you need to go in front of managers or directors to explain what happened, it may not meet the mark.

The following articles explain how to do this:. I removed status , as those are successful. What I am after here are the requests which are something other than OK. The result of the query is illustrated in Figure There are a number of additional parameters which you can pass to LogParser that affect the image. For example, legend, groupSize, config, etc This command will also provide a list of the different chart types.

Figure LogParser 3D pie chart. Another useful chart is the ratio between cached and actual requests. Recall from the Data Analysis section where I discussed that an HTTP Status code of means that the requested files are retrieved from the server however, a is retrieved from the client. Figure 11 shows the LogParser query for the creation of this chart. Notice that I used the -values parameter. Although the difference between HTTP Status code and are clearly visible, I thought it may add some value to include the number of hits for each.

Figure 12 illustrates the output of the previous LogParser query. I think you are getting the picture now about how charting the IIS Logs using LogParser can help convey what is happening much better than a table of data. But before I stop, I want to show you one more example using the Column chart type.

Figure LogParser 3D column chart. At the beginning of this section I mentioned that the installation of the Office Web Component OWC is a requirement if you want to use the LogParser charting capabilities. In your organization, there may be restrictions that prohibit this or you simply might not want to install it. Figure 16 shows what this looks like. Select the status. Import the 'comma' delimited CSV file and you will end up with the Status in column A and the number of occurrences for each status in column B.

This assumes you executed the LogParser query shown in Figure Lastly, select all the data from column A and B, including the headers and choose the type of Pie chart to create. Figure 17 , illustrates how this may look. The end result is a Pie chart, Figure 18 that is similar to that shown previously in Figure There are many options in regards to color, chart type, labels, etc. With a click of a button you can change the chart type from Pie to Bar or to Line.

There are a lot of options for creating professional looking charts within Excel. There are so many options and possibilities for analyzing and presenting the results of that analysis using LogParser. For some additional tips and examples, check out these articles written by Robert McMurray.

There is also a very useful help file and many prewritten scripts provided within the installation package of LogParser. The next section will discuss this and other topics in more detail. When you install LogParser 2. IIS 6 or Windows Server is no longer receiving any updates from Microsoft but supports IPV6 and most security measures needed for simple hosting needs on a budget. IIS 7 shipped with Windows Vista and has better support for the.

IIS 7. Extended support will end in this is the oldest version receiving any support officially from microsoft. Support will last until If you are a business owner consider purchasing the newest version your hardware can run. Virtual Directories IIS allows you to create sites, applications, and virtual directories to share information with users over the Internet or internally on an intranet such as a home network.

Ports Typically your server will use port 80 for HTTP traffic however this can be adjusted to meet your needs or the needs of another application on your computer.
