IIS 6.0 and Flash streaming (FLV)

ajaymohanty — Wed, 22 Oct 2008 11:38:01 +0000

Problem:
We recently acquired an app that streams flash – but it was not working on our web servers (Winows 2003, Standard). It was pretty aggravating to get up and running (*Opens arms for Silverlight*).

The site has .swf files that stream a flash video (.flv). The SWF works just fine, but the FLV won’t stream. There wasn’t a MIME type for .FLV in IIS.

Solution:
1. Open IIS Manager on the server
2. Expand the Local Computer Server.
3. Examine the ‘Properties’ of the local server
4. Select the MIME Types tab.
5. Click the ‘New’ button and enter the following:
* Associated Extension box: .FLV
* MIME Type box: flv-application/octet-stream
6. Click Ok and restart IIS.

Ctrl+Enter not working in IE

Method-01

1. Go to the “Tools” menu on Internet Explorer then select “Internet Options”
2. Go to the Advanced tab .
3. Under Browsing make sure you got a check on “Use inline AutoComplete”
4. Hit OK.

Method-02

Registry fix.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
“Append Completion”=”no”
“Use AutoComplete”=”yes”
“AutoSuggest”=”no”

Changing “Append Completion” from “no” to “yes” will restore the function.
