Not all links work in the iframed

Hi,

I was iframing amazon.com and I noticed not all links work within the iframe.

I also noticed that the URL of the links that do not work are very long (for products) such as:
http://www.amazon.com/gp/product/B002RJ9T5Y/ref=s9_psimh_gw_p201_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=1Y58T8QPN4ZEWT3AJKN3&pf_rd_t=101&pf_rd_p=1389517282&pf_rd_i=507846

Other links such as this one (for categories):

http://www.amazon.com/s/ref=sr_nr_n_0?rh=n%3A1036592%2Cp_6%3AATVPDKIKX0DER%2Cn%3A%211036682%2Cn%3A1040660%2Cn%3A2368343011&bbn=1040660&ie=UTF8&qid=1374122322&rnid=1040660

work perfectly.

Any ideas of how to solve this issue?
