I use the server to access a site's level two page, why always be transferred to its home page

I use a server to access a site's level two page, why is it always transferred to its home page?

Is this a swollen thing??

Do you directly enter a two-level domain name to access the correct address?

Can look at the address of the label is really you want to access the level two page <br>------Solutions----------------------<br> The other side has JS code, do not let you put on the frames page <br>--- ---solutions----------------------<br> your IFRAME website is your own? <br/> If not, it is possible that the forbid may have been mediated by the IFRAME. <br/><br/> For example the side of the page added <br/><pre class= "Brush:javascript" ><br/> <br/></pre ><li ><i class= "Layui-icon" >& #xe63a;
