I have noticed that my blog www.minterest.com is very slow in loading even after the first visit then I came to know that i cant access my site offline from IE Cache... Then I have gone through the source of my page and then come across the codes <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> I found that it is presented in the header file... So is this the reason?? If i remove these codes then will that increase the speed of my site and also enable offline browsing??? And is there any problem if we delete these codes?
Removing those meta tags will not increase the speed of the site. Those tags tell proxy servers not to store a copy of your site in their cache. You may get some speed increases by using the Wordpress cache as explained here http://codex.wordpress.org/Function_Reference/WP_Cache/ You may also want to disable your plugins one at a time to see if one of them is the cause of the problem.
I was right just delete these codes <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> from your header.php and it will boost the speed of your blog.. I have just tried the same...
Well, it loads really fast for me. Loads fast with Firefox and IE. Maybe you should clear your cache and temp files on your computer?
