Greets, I'm pondering the use of squid as a reverse proxy (for accelerated content delivery), but need to dynamically update online text advertisements which appear on the static pages delivered to users. The idea is to embed a token of sorts in the static page. Then, perhaps using a plugin or something, the token is dynamically updated to display the latest text advertisement/s. The advertisement content is provided by external servers, so the squid plugin/module will need to fetch the ads based on token arguments, etc. Has anyone done something similar or is there a plugin/module which can be used and/or hacked to achieve this? I believe Google does something similar for their ad delivery. Any comments or suggestions are welcome.
This is where AJAX and Web2.0 stuff actually has some use. A static long-term cacheable page with known IDs spread around as needed. Combined with ajax calls that load some things to fill the HTML containers with.
NP: the only relation this has to squid is which objects are cacheable, for how long and which are not. You get to decide on all that by yourself though.
An alternative that has a lot more to do with Squid is ESI. Which Squid caches the templates and various bits with their own caching times and generates the final client pages as requested. ESI in Squid has a few known bugs which prevent the more complex stuff from working. But for simple uses like you ask it's happy and working in some large production sites.
