Just a side note: because you're using the key in the "key" URI
argument below, you should escape it because the value may contain
special characters. That is,

set_escape_uri $key $uri$args;

And then in your location = /memc, you should unescape the "key" URI
argument like this:

set_unescape_uri $key $arg_key;

You can use the srcache_store_skip directive to achieve this:

http://wiki.nginx.org/HttpSRCacheModule#srcache_store_skip

Basically, you can do something like this:

map $upstream_http_content_type $no_store {
default 1;
~*html 0;
}

server {
...
location / {
set_escape_uri $key $uri$args;
srcache_fetch GET /memc key=$key;
srcache_store PUT /memc key=$key&exptime=$ttl_1m;
proxy_pass http://www.example.com;

srcache_store_skip $no_store;
}
}
