In this case, however, the spacing is apparently so that there are no similarly anthropomorphic adjacent machines forced to closely listen to this server's inanely simple and over-cheery chatter.&amp;#160; &amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The title text is a joke that all the other servers in the rack would think the web server is being childish. &amp;lt;tt&amp;gt;/var/log/syslog&amp;lt;/tt&amp;gt; is where Linux (used by the vast majority of servers) and other POSIX systems store their system log messages.

Often, they would automatically suggest to load the mobile version of the website, but then serve the front page of the mobile site and not the page the user had requested. In quite a few sites, there would be no 1-to-1 correspondence of pages between the regular and the mobile site, so this problem is difficult to solve and very annoying. Since the date of this comic, mobile versions of websites have improved significantly, so the types of problems discussed in the comic rarely happen, although the difficulty of persuading the browser and/or server to ''not'' customise web-pages for mobile usage (e.g., assuming the display is going to be in portrait orientation, so restyling it accordingly) is often a continuing problem.

HTTP is a {{w|stateless protocol}}. After serving the web page, the connection is severed. Any new request for a page will have to start afresh - which is where the server starts with again: &amp;quot;Hi! I'm a server!&amp;quot; Of course, browsers do not have egos nor do they hold grudges &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;{{citation needed}} &lt;/ins&gt;but it can be annoying for users. This design issue can also slow down the browsing experience.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The title text is a joke that all the other servers in the rack think the web server is being childish. &amp;lt;tt&amp;gt;/var/log/syslog&amp;lt;/tt&amp;gt; is where Linux (used by the vast majority of servers) and other POSIX systems store their system log messages. The 'trying to start conversation' comment is probably a joke on {{w|Address Resolution Protocol|ARP}} discovery packets that are sent out to the network to see who is who. All servers send out ARP packets to see what other machines are on the network, but some machines send them out every 5 minutes, which can be extremely annoying for someone monitoring network traffic logs.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The title text is a joke that all the other servers in the rack think the web server is being childish. &amp;lt;tt&amp;gt;/var/log/syslog&amp;lt;/tt&amp;gt; is where Linux (used by the vast majority of servers) and other POSIX systems store their system log messages.
