Users - Static Content URLs
Locked
 
|
I came across this setting in the url.properties file and wanted to know if it would solve a problem for me.
# Static Content URLs to make it easy to move the serving load for static content to other machines # -- thse are for general content such as images, js & css files, or non-dynamic HTML files content.url.prefix.secure= content.url.prefix.standard=
My image files are sitting on a different server from my OFBIZ system. How can I efficiently reference them so they don’t add overhead to the server or network connection?
Right now I reference them by adding the URL in product settings, but does this setting help make things faster/easier…. If not, what does?

Mark,
Sitting apache in front of the app server gives you a few options... We use Apache with mod_proxy and mod_rewrite, this allows us to reference static files from a different location. I think you can do the same with AJP although someone else will probably know more about this... -- Kind Regards Andrew Sykes <[hidden email]> Sykes Development Ltd http://www.sykesdevelopment.com _______________________________________________ Users mailing list [hidden email] http://lists.ofbiz.org/mailman/listinfo/users |

The whole point of these prefixes are to point to a different server for content, even a server in another data center or an edge routed server/service like Akamai. -David On Jan 25, 2006, at 12:08 PM, Mark Mantarro wrote: > I came across this setting in the url.properties file and wanted to > know if it would solve a problem for me. > > > # Static Content URLs to make it easy to move the serving load for > static content to other machines > > # -- thse are for general content such as images, js & css files, > or non-dynamic HTML files > > content.url.prefix.secure= > > content.url.prefix.standard= > > > My image files are sitting on a different server from my OFBIZ > system.

Still not sure on how to setup... This will automatically prefix whatever I
have in product url? (e.g. in url.properties I would set up http://myexternalserver.com/images In the product URL I would have small url: /thumb/xxx.jpg med url: /med/xxx.jpg ) So then then OFBiz would know the xxx.jpg files exist off the app server and put together the correct small url of... http://myexternalserver.com/images/thumb/xxx.jpg Is that all there is to the setup?

Yeah, it's pretty much that simple. It just appends the image URL for the product to the prefix in the url.properties file (or it can also be set per webapp on the WebSite entity). -David On Jan 25, 2006, at 2:03 PM, Mark Mantarro wrote: > Still not sure on how to setup...

Mark,
Once you have that prefix, if you want the images to be hosted elsewhere, you need to have something on your server that intercepts the request before it reaches tomcat and then "proxies" that request elsewhere based on a rule identifying that prefix. The "something" used to intercept the request is more-often-than-not the Apache Web Server. Using Apache, you have two options for passing and filtering requests. 1/ AJP13, This is the most common approach using the bespoke ajp13 protocol to pass requests to a java app server, OFBiz is pretty much configured ajp13 ready. 2/ mod_proxy/mod_rewrite. This is a more powerful setup for doing all sorts of fancy load balancing tricks and URL rewriting via regexps. The biggest drawback of this setup - Apache is acting as a proxy and therefore modifies the request-header so OFBiz records all requests as coming from the proxy rather than the client - which is pretty useless if you need an ip for some reason! Bear in mind that in 2/ SSL certs need to be installed with Apache, not with Tomcat (otherwise Apache is a man-in-the-middle). I can't remember where they go in 1/ but I'm guessing it's Tomcat (hopefully someone can confirm) I hope that helps. -- Kind Regards Andrew Sykes <[hidden email]> Sykes Development Ltd http://www.sykesdevelopment.com _______________________________________________ Users mailing list [hidden email] http://lists.ofbiz.org/mailman/listinfo/users |

We do host the static content on one of our sites, with the method
you've mentioned below, on another server altogether. We use the dns address management to take care of redirection rather than using Apache to proxy/redirect it. Basically once ofbiz has returned the page the clients browser sends it's content requests to another server. The app server is still fronted by Apache and linked to ofbiz through ajp13, as that leaves us with plenty of flexibility to manage other sites and services at the front end. We've left the secure content url alone as we don't have ssl configured on the static content server and generally most of the load comes from people shopping/browsing in non-ssl pages. Just a simple synch to keep the two servers inline with regards to static content. Ray Mark Mantarro wrote: >Still not sure on how to setup...

Ok,
This seems to now be outside the scope of OFBIZ, but it is important for others like me who are trying to bring up an instance for the first time. So based on David and Andrew's responses this is my understanding. You can prefix all Static Content by adding a URL prefix in the settings of Website ( Standard Content Prefix ). Once set, you can store your images in a place independent of OFBIZ. HOWEVER, this will not reduce the traffic on the OFBIZ server because the included webserver/servlet (Catalina/Jetty) is still handling to movement of the images. To truly move that load, you must ALSO use one of the strategies below. (I will have to research these as I am more of a database person and a bit light on webapps.) Let me know if I missed the point. Thanks for all your responses.

Mark,
Yes, it sounds like you've got the idea. Remember also to consider the third strategy suggested by Ray i.e. using DNS management to redirect based on the content prefix. Ray: I'd be interested to hear how painful (or otherwise) the DNS route is... Good luck with it all Mark. -- Kind Regards Andrew Sykes <[hidden email]> Sykes Development Ltd http://www.sykesdevelopment.com _______________________________________________ Users mailing list [hidden email] http://lists.ofbiz.org/mailman/listinfo/users |

Mark,
My last reply does point out that you can remove the traffic load by making the url point to a different dns name. To be more clear lets say the main site is: www.ourmainsite.com - some IP like 123.123.123.123, running ofbiz, maybe Apache if preferred. content site is: images.ourmainsite.com - some other IP like 456.456.456.456, running just Apache. This way the first page request hits the ofbiz 123.123. 123. 123 server, it returns the dynamic html page and the browser then requests the page content (images, css) etc from the content server 456.456.456.456.

Sorry I misunderstood (Ray), I thought you were referring to a DNS based load balancer...

Sorry, nothing as complicated as a DNS load balancer, in summary a very simple solution as no proxy or reg-exp to set up either. I didn't have a need to make it complicated just thought it worth while removing some of the traffic from the main server, which was a little stretched at times.

Mark,
On the subject of the mod_proxy/mod_rewrite approach, I've submitted a patch allowing OFBiz to get the client ip (rather than the proxy ip) when a proxy is used (SVN rev 6595), so the ip objection to using a proxy is no longer relevant. -- Kind Regards Andrew Sykes <[hidden email]> Sykes Development Ltd http://www.sykesdevelopment.com _______________________________________________ Users mailing list [hidden email] http://lists.ofbiz.org/mailman/listinfo/users |
