Hi, this is my first post so forgive me if I posted in the wrong spot.
I am contemplating writing an RFC on an HTML tag to be placed in the <head> of a webpage which gives the browser instructions on a single location were the page may obtain bulk cache information from the server instead of having each time a new cache-able element is requested having the browser create a new http request to the server to only have the server respond with a 304 Not Modified.
I am not going into detail but a quick over view would look something like (taken from google.com homepage's cache-able files):
<head>
...
<cache src="">
<file href="" style="font-size:12px;white-space:pre-wrap;font-family:Consolas,'Lucida Console',monospace">images/srpr/logo3w.png" />
<file href="" style="color:rgb(0,0,0);font-family:Consolas,'Lucida Console',monospace;font-size:12px;white-space:pre-wrap">xjs/_/js/s/c,sb,cr,vm,cdos,jsa,sf,tbpr,tbui,rsn,ob,mb,lc,hv,cfm,klc,kat,aut,esp,erh,bihu,amcl,kp,lu,m,rtis,shb,sfa,hsm,j,p,pcc,csi/rt=j/ver=K-W_gw26Qd4.en_US./d=1/sv=1/rs=AItRSTP1F4RezC8aHlgXoNQaBhX3N9n9sQ" />
<file href="" style="color:rgb(0,0,0);font-family:Consolas,'Lucida Console',monospace;font-size:12px;white-space:pre-wrap">extern_chrome/edf8435073bcf94.js" />
<file href="" style="color:rgb(0,0,0);font-family:Consolas,'Lucida Console',monospace;font-size:12px;white-space:pre-wrap">xjs/_/js/s/sy10,gf,sy45,sy46,sy81,sy44,sy39,sy82,sy8,sy34,sy50,sy48,sy80,sy99,sy105,sy108,sy9,sy15,mbtt,ssi,ifl/rt=j/ver=K-W_gw26Qd4.en_US./d=0/sv=1/rs=AItRSTP1F4RezC8aHlgXoNQaBhX3N9n9sQ" />
<file href="" style="color:rgb(0,0,0);font-family:Consolas,'Lucida Console',monospace;font-size:12px;white-space:pre-wrap">textinputassistant/tia.png" />
<file href="" style="color:rgb(0,0,0);font-family:Consolas,'Lucida Console',monospace;font-size:12px;white-space:pre-wrap">images/nav_logo114.png" />
</cache>
...
</head>
The browser would then block until it cross references it's own cache with the listed files and (if > 1) send a request to the location specified in the "src" attribute in the "cache" tag with the cross referenced files list and the associated "if-modified-since" date of each file. The server would then respond telling the browser to use the cache for the files that can be used for cache. Any other files need to be loaded load like normal.
The idea would be to have a page with many images, _javascript_, css, exc... to do a single request in the hopes that the it could save any of those cache-able files from needing their own request to the server to see if they have been modified.
If there is already an RFC for this a link to it would be appreciated as I looked for one and came up with only http header cache controls which does not work the same way.
