On a project I'm on (private web based application accessed by 1,000s of users) we're looking to shard off the loading of static content to a separate server (e.g. as a CDN) for improved performance.

I'm only looking to serve up static (.JS, .CSS, .GIF, .JPG, & .PNG files) that will rarely change, and will hopefully be heavily cached by the end users.

Therefore I'd like to be able to set this up to not serve up cookies, gzip the text based files, and set the outbound cache headers to 12mo. (filenames are versioned)... and enable a decent server-side cache.

With this being rolled out, the OS and Web Server to be used are up for grabs. My default thoughts we're... well, duh Apache on Linux... but in my recent research I've read some not flattering things about Apache (when compared to other servers) (Lighttpd).

We can't be the first team to have setup a dedicated static Web Server (/pool) thus I'm hoping others have some stats to compare.

If I believe the stats I read so far (none are really unbiased 3rd party), it appears that the raw speed and ability to handle concurrent connections places the servers in this order.

  1. Cherokee
  2. Lighttpd
  3. Nginx
  4. Apache

I'm not even sure where IIS, Tomcat, Jetty, LiteSpeed, etc. fit into the rankings.

Now I realize there are other considerations (OS lock-in, $$$/licensing, ease of use & community knowledge) but outside those...

Question:

Has anyone here done any speed comparisons (e.g. with HTTP Test Tool, ApacheBench or similar) against these servers and has info they can share about which is faster at serving static content or noticed any alarming memory usage etc.?

I'm trying to debug a strange rendering/interaction issue with a web application in IE and thought I'd peek at the event viewer in Windows (XP) to see if anything odd was happening at the same time.

I see categories for System, Security, Application etc. but I also see one for "Internet Explorer", but there are no events, and if I view the properties, I can't set a log file name... (thus I presume I can't log events)

Is there a magic setting somewhere in IE to allow this to work? Or is this category auto-generated by some other application and it just isn't hooked up properly?

PS The strange issue (for the curious) is that a popup window in a web app very randomly, on only one client site, after extended use, all of a sudden renders/paints completely black. The HTML source is still there, and isn't set to <body bgcolor="#000000;...> but any interaction with the popup fails and IE needs to be completely restarted in order to fix it.

I do want Internet Explorer to maintain a history for websites I visit (e.g. to enhance performance with caching and provide quick access back to places I've recently visited)

However I have never, ever wanted Internet Explorer to track history for files it didn't even open!

e.g. when I view txt files, xml files, videos, mp3 files, doc files, spreadsheets etc... by "launching" them from elsewhere in Windows (e.g. Windows Exploring (the file manager, not the browser), or from Firefox, Chrome, etc. when they pass along a file to be handled outside the browser).

I'm open to running scripts daily to purge the bogus entries but ideally a one time regedit or similar fix would be preferred.

This is hopefully a real easy one.

In Windows XP on some environments the File Properties dialog (that opens on right-click > properties when viewing the file in windows explorer) sometimes shows a Security Tab and sometimes not.

How does one enable it? (I need to allow "run" access on certain types)

Note 1: I'm logged in with Administrator privileges

Note 2: I'm running NTFS on both machines

Note 3: Running XP Professional on both machines

PS I found one source Googling that suggests this will work but I didn't have any luck;

UPDATE: After 2 reboots... based on the 5 steps below... the Security Tab did appear.

  1. Launch Windows Explorer or My Computer.
  2. Click on the Tools at the menu bar, then click on Folder Options.
  3. Click on View tab.
  4. In the Advanced Settings section at the bottom of the list, uncheck and unselect (clear the tick) on the “Use simple file sharing (Recommended)” check box.
  5. Click OK.

(I've linked to two screenshots found on the web of the dialog I'm talking about)
