'''NetCache''' is a former [[web cache]] software product which was owned and developed by [[NetApp]] between 1997 and 2006, and a hardware product family incorporating the NetCache software.
==History==
The NetCache software started as a commercial [[fork (software)|fork]] of the [[Harvest Object Cache]]<ref>{{cite web|url=http://www.usenix.org/publications/library/proceedings/usenix-nt97/usage_abstracts/Brian_Wink.html |title=Brian Wink |publisher=Usenix.org |date= |accessdate=2012-08-07}}</ref><ref>{{cite web | title=NetCache Technical Paper | url=http://www.linofee.org/~jel/da/papers/netcache1.ps.gz | accessdate=2009-05-05}}</ref> developed by Internet Middleware Corporation (IMC), which consisted of former Harvest project developers including Peter B. Danzig, a professor at University of Southern California.<ref name="nw">{{cite journal | journal = [[Network World]] | date = 21 July 1997 | author = Chris Nermey | title = New Web Caching boxes promise better bandwidth control }}</ref>  In late 1996 the software was named '''Internet Middleware Object Cache''',<ref>{{cite web|url=http://www.netcache.com/ |accessdate=2012-08-07 |title=Internet Middleware Object Cache: Cached-2. |publisher=Internet Middleware Corporation |date=September 10, 1996 |url-status=dead |archiveurl=https://web.archive.org/web/19961112032719/http://www.netcache.com/ |archivedate=November 12, 1996 }}</ref> and it was referred to as Cached 2 and later Cached 3.<ref>{{cite web |url=http://excalibur.usc.edu/ |title=The Harvest Cache and Httpd-Accelerator |date=1996-11-22 |accessdate=2012-08-07 |url-status=dead |archiveurl=https://web.archive.org/web/19961122024331/http://excalibur.usc.edu/ |archivedate=November 22, 1996 }}</ref><ref>{{Cite web |url=http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.57.1141&rep=rep1&type=ps |title=Building a web cache system - Architectural Considerations |citeseerx=10.1.1.57.1141 |access-date=2010-08-23 |archive-date=2012-10-08 |archive-url=https://web.archive.org/web/20121008132853/http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.57.1141&rep=rep1&type=ps |url-status=dead }}</ref>
In 1997 IMC was acquired by [[NetApp]], and the software was renamed NetCache, with Danzig becoming chief architect and CTO of NetCache division.<ref name="nw"/>
In 2006 NetApp sold the NetCache business (but not technology) to [[Blue Coat Systems]],<ref>{{cite news | url = https://www.theregister.co.uk/2006/06/23/netapp_sells_netcache/ | title = NetApp flogs NetCache to Blue Coat | newspaper = The Register | date = 23 June 2006 | author = Chris Williams }}</ref><ref>{{cite news | url = http://www.arnnet.com.au/article/167954/blue_coat_looks_partners_help_netcache_transition/ | title = Blue Coat looks for partners to help NetCache transition | author = Rebecca Munro | publisher = [[ARNnet]] | date = 19 October 2006 }}</ref> who had a similar line of [[ProxySG]] appliances which became the more expensive product for existing NetApp customers.<ref>{{cite news | url = http://news.techworld.com/networking/6297/netapp-sells-netcache-to-blue-coat/?siteSection= | title = NetApp sells NetCache to Blue Coat | author = Bryan Betts | publisher = Techworld | date = 26 June 2006 | access-date = 25 August 2010 | archive-date = 10 March 2012 | archive-url = https://web.archive.org/web/20120310063831/http://news.techworld.com/networking/6297/netapp-sells-netcache-to-blue-coat/?siteSection= | url-status = dead }}</ref>
==Hardware appliance==
The hardware NetCache appliance included the NetApp [[Data ONTAP]] microkernel, with its [[Write Anywhere File Layout]] file system, achieving four times the throughput as software equivalents available at time, according to NetApp comparisons.<ref>{{cite web | title = NetCache Architecture and Deployment | citeseerx = 10.1.1.27.8507 | author = Peter Danzig | date = February 1997 }}; also {{cite journal | journal = Computer Networks and ISDN Systems | volume = 30 | issue = 22–23 | date = 25 November 1998 | pages = 2081–2091 | doi = 10.1016/S0169-7552(98)00250-5 | archiveurl = https://web.archive.org/web/19990508132725/http://www01.netapp.com/technology/level3/3029.html | url = http://www01.netapp.com/technology/level3/3029.html | title = NetCache Architecture and Deployment | archivedate = 1999-05-08 | url-status = dead | last1 = Danzig | first1 = Peter | citeseerx = 10.1.1.27.8507 }}</ref> Starting with [[ONTAP]] version 9.5 similar functionality was introduced under [[ONTAP#FlexCache Volumes|FlexCache]] name.
