ENABLING GZIP FOR FASTER DOWNLOAD

ENABLING GZIP FOR FASTER DOWNLOAD OF WEB PAGE.


Zombi note :The HTTP/1.1 protocol allows for clients to optionally request the compression of content from the server. The standard itself specifies two compression methods: “gzip” and “deflate” Both are supported by many HTTP client libraries and almost all modern browsers.


Enabling gzip at IIS Manager
At IIS Manager (inetmgr.exe) open Web Sites Properties, at Service tab mark Compress application files & Compress static files.
Zombie note :You need to right click the web sites rather than going into specific site and click properties of perticlar website.

Now you need to edit one xml file as below
c:\WINDOWS\system32\inetsrv\MetaBase.xml file.




Zombie note : Before Editing Metabase.xml file stop IIS Services or enable Direct Metabase Edit at Web by going into the peroperties and WEB02 dialog box will appear and check mark the “ENABLE DIRECT METABASE EDIT.”

Edit Metabase.xml with text editor and locate the following lines:
HcFileExtensions
HcScriptFileExtensions
Both of thes keys are mentiond twice in Metabase.xml, for gzip ompression and deflate compression, add the file extention fo gzip compression.

FOLLING SHOWS HOW IT WILL LOOK LIKE

IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/deflate"
HcCompressionDll="%windir%\system32\inetsrv\gzip.dll"
HcCreateFlags="0"
HcDoDynamicCompression="TRUE"
HcDoOnDemandCompression="TRUE"
HcDoStaticCompression="FALSE"
HcDynamicCompressionLevel="0"
HcFileExtensions="htm
html
txt
xml
css
js"
HcOnDemandCompLevel="10"
HcPriority="1"
HcScriptFileExtensions="asp
dll
exe
aspx
php"
>

HcCompressionDll="%windir%\system32\inetsrv\gzip.dll"
HcCreateFlags="1"
HcDoDynamicCompression="TRUE"
HcDoOnDemandCompression="TRUE"
HcDoStaticCompression="TRUE"
HcDynamicCompressionLevel="0"
HcFileExtensions="htm
html
txt
xml
css
js"
HcOnDemandCompLevel="10"
HcPriority="1"
HcScriptFileExtensions="asp
dll
exe
aspx
php"
>



To enable or disable gzip per web site
cscript C:\Inetpub\AdminScripts\adsutil.vbs set w3svc/site#/root/DoStaticCompression False
cscript C:\Inetpub\AdminScripts\adsutil.vbs set w3svc/site#/root/DoDynamicCompression False
adding file extention to be compressed can be preformed with this command:
cscript C:\Inetpub\AdminScripts\adsutil.vbs set W3Svc/Filters/Compression/GZIP/HcFileExtensions "htm" "txt" "doc"


CHHERS…NOW TRY TO BROWSE YOUR SITE AND VOOOIIILLLAAAA,IT IS FASTER THAN BEFORE….ENJOYYYYY

  Hi Team, Today i am going to share one of the nightmarish issue with you all, We are having Sitecore 9.1.1 hosted in azure PaaS environment Our site was working just fine and no noise, but we have been working on a feature release where 7-8 months of development needed to be released to production, Big GO LIVE event right?  Also to make the development smoother we also introduced BLUE/GREEN deployment slots in the same release, so we can easily SWAP slots and go live Everything went well, we went live, we even did load and performance testing on our staging and pre-prod and we were confident enough of results Very next day we started getting "SITE DOWN" alerts, and also product owners and clients mentioned that site is very slow for them in US time and in our morning when we were accessing it, it was working lighting fast so we were clue less at start, but we started digging  1) First thing caught our eyes were HIGH CPU spikes, in US time, also without any traffic CPU u...
