node.js - Change URL after POST using ExpressJS -

i use expressjs nodejs server. user sends me login info through post , after checking credentials render page: router.post("/login", function (req: request, res: response, next) { if(credentialsok){ res.render('main'); } }); the problem url becomes http://myaddress/login , remove /login of address. don't want use redirect want send local variables through render. how can change url? you can still pass local variables through res.redirect . router.post("/login", function (req: request, res: response, next) { if(credentialsok){ req.session.localvar = yourlocalvar; res.redirect('/main'); } }); then in main router: router.get("/main", function (req: request, res: response, next) { var yourlocalvar = req.session.localvar; res.render('main'); });

i want detect terms in polynomial expression x^2+3x-2 i want string seperated sub-strings @ '+' , '-'. in other words, want have terms seperately. simplify things, add '+' or '-' @ start of string if not present simplify things. +x^2+3x-2 now, need regex can detect terms seperately. need keep in mind there can many terms possible. i did try [+-]?(.+?) but since new regex, don't think within capability make work. i need help. please note in case, desired results : +x^2 +3x -2 thanks in advance! a regular expression can limited job state, joseph's answer shows. but if want handle more complicated expressions regex wont cut it. consider x^(-2)+3x-2 or unexpanded expression such as x^2+3(x-2)-2 these require parser: see regular expression vs. string parsing

css - Inherit text-shadow with units relative to a child element without selecting all children -

i want create text shadow element, , want children of element inherit shadow. issue relative units (i.e.: em, ex, ch) of inherited text-shadow relative calculated font-size of element created on (i.e.: parent element). also, understand that parent, parent * { text-shadow: 1em 2em 3em currentcolor; } will work fine, i'd prefer avoid * selector. don't want select every single child element, more importantly, don't want mess specificity. (how) possible? (i unable comment restriction of 50 poitns comments, hence question in answer tab & possible solution update based on answers:p) so @uber5001, question 1: clarity, selecting child elements or not? first line did say, want select child elements. , @ end of question said, don't want select children of parent element. sorry couldn't understand meant that. in jsfiddle provided in comments, adding text-shadow: 5em 0em 0em #999; #parent p:first-child gives desired effect. http://jsfiddle

Pagination With Php using Redis DB -

i want display list of customers pagination .structure of db follow: redis:> hset customerlist username userid (where username:almas userid:1) redis:> hmset customerlog:1 userid value1 name value2 contactno value3 (where value1:1 , value2: almas sayyad, value3: 8676756556) i have used hash set , want continue same datatype. greatfull if 1 can give me solution this. tl;dr paginating hash isn't trivial - should consider using different data structure more suitable task, namely sorted set. hashes have no order , way sanely iterate fields hscan . however, scanning unordered, can return duplicates , number of results each call varies - building pagination mechanism on top of challenging , inefficient. you can keep data, i.e. users, in hash, store field names in sorted set well. can give each user score order them or use lexicographical ordering - either way, you'll able paginate sorted set.
