Here is my quick hack of your code to allow forms to be submitted using the javascript trick.

string url; // Our base http-in url
integer r;  // Used for uniqueness in PrimMedia urls
integer page;  // The page number.
 
show(string html)
{
    html += "<span " + (string)((++r) % 10) + "/>";
 
    llSetPrimMediaParams(0,                  // Side to display the media on.
            [PRIM_MEDIA_AUTO_PLAY,TRUE,      // Show this page immediately
             PRIM_MEDIA_CURRENT_URL,html,    // The url if they hit 'home'
             PRIM_MEDIA_HOME_URL,html,       // The url currently showing
             PRIM_MEDIA_HEIGHT_PIXELS,512,   // Height/width of media texture will be
             PRIM_MEDIA_WIDTH_PIXELS,512]);  //   rounded up to nearest power of 2.
}
 
// This creates a data: url that will render the output of the http-in url 
// given.
string build_url(string url)
{
    return "data:text/html," 
        + llEscapeURL("<html><head><script src='" + url 
        + "' type='text/javascript'></script></head><body onload='init()'></body></html>");
}
 
// This wraps the html you want to display so that it will be shown from links 
// made with build_url
string build_response(string body)
{
    return "function init() {document.getElementsByTagName('body')[0].innerHTML='" + body + "';}";
}
 
 
string replace_all(string src, string target, string replace)
{
    return llDumpList2String(llParseString2List(src,[target],[]),replace);
}

string get_query(key id, string name)
{
    string query = llGetHTTPHeader(id,"x-query-string");
    query = replace_all(query,"+"," ");
    query = llUnescapeURL(query);
    list q = llParseString2List(query,["=","&",";"],[]);
    integer i = llListFindList(q,[name]);
    if (i != -1)
    {
        return llList2String(q,i+1);
    }
 
    return "";
}

{
    state_entry()
    {
        llRequestURL();
        llOwnerSay("Ready");
    }
 
    http_request(key id, string method, string body)
    {
        if (method == URL_REQUEST_GRANTED)
        {
            url = body + "/";
 
            show(build_url(url + "page" + (string)(page)));
        }
        else if (method == "GET")
        {
            //Check for submited form value here
            string float_text=get_query(id,"text");
            if (float_text!="")
            {                
                llSetText(float_text,<1,1,0>,1);

            string path = llGetHTTPHeader(id,"x-path-info");
            string content = "<h1>path: " + path + "</h1>";
            page = (integer)llGetSubString(path,5,5);
            if (page > 0) content += "<a href=\"" + build_url(url + "page" + (string)(page - 1)) + "\">Previous</a> ";
            if (page < 9) content += "<a href=\"" + build_url(url + "page" + (string)(page + 1)) + "\">Next</a><br>";
            integer k;
            for(;k<10;++k)
            {
                if (k == page)
                    content += "<br>Page " + (string)k;
                else
                    content += "<br><a href=\"" + build_url(url + "page" + (string)(k)) + "\">Page " + (string)k + "</a>";
            }
            content += "<h1><form action=\""+url+"\" method=\"GET\">Floating Text:<input type=\"text\" name=\"text\"><br><input type=\"submit\" value=\"Set\"></form></h1>";
            content += "<br><br>This page is " + (string)(llStringLength(build_response(content)) + 37) + " bytes long.";
            
            
            
                 
            
            llHTTPResponse(id,200,build_response(content));
            
            
        }
    }
}

In regards to needing to use llEscapeURL.

There are specific characters that must be encoded when included in a URL. llEscapeURL encodes MORE than what is needed.

Specifically llEscapeURL only leaves [0-9a-zA-Z] as not encoded.

Other characters can be left not encoded as well - $-_.+!*'(),

See the following link for more information.
